No, this isn't possible out of the box. Superset's download controls are gated by role permissions and feature flags, not by chart/viz type, so you can't natively allow "Download as image" on Bar/Line charts while hiding it on Tables.

Here's how the Download menu on a dashboard chart works:

• The entire Download submenu only appears when the user's role has can_csv on Superset (your existing permission) [1].
• Within it, "Export to .CSV" and "Export to Excel" always show; "Export to Pivoted .CSV" only shows for Pivot Tables; "Export to full .CSV/Excel" only shows for Table charts when ALLOW_FULL_CSV_EXPORT is enabled [2].
• "Download as image" is unconditional — it renders for every chart type once the Download submenu is visible. There's no viz_type check gating it [3].
• The usePermissions hook backs this with a single boolean canDownload tied to can_csv — no per-chart-type or per-format granularity [4].

So can_csv is an all-or-nothing switch for the whole Download submenu (CSV, Excel, and image) across every chart on the dashboard.

Two things worth knowing:

1. Granular export controls — Superset has introduced more granular permissions (can_export_data, can_export_image, can_copy_clipboard) behind the GRANULAR_EXPORT_CONTROLS feature flag [5] [6]. This splits image export from data export, but it's still not per-chart-type — disabling can_export_image would hide "Download as image" for all charts, not just Table. The dashboard download button also respects this flag [7].

2. VIZ_TYPE_DENYLIST in superset/config.py prevents a viz type from being used entirely [8] — not what you want, since you still want Table charts visible.

To get exactly the behavior you're describing (image download disabled on Table only, enabled on Bar/Line), you'd need to customize the frontend — specifically, patch SliceHeaderControls to add a viz_type check around the DownloadAsImage menu item [3]. There's no existing permission or config surface for per-chart-type download control.

Would you like me to dig into what that frontend change would look like?

give this answer in context to superset 5

In Superset 5, the same limitation applies — there's no per-chart-type control over "Download as image."

In SliceHeaderControls, the entire Download submenu (CSV, Excel, and image) is gated by a single check — props.supersetCanCSV, which maps to the can_csv permission on Superset [1]:

{props.supersetCanCSV && (
  <Menu.SubMenu title={t('Download')} key={MenuKeys.Download}>
    <Menu.Item key={MenuKeys.ExportCsv}>{t('Export to .CSV')}</Menu.Item>
    ...
    <Menu.Item key={MenuKeys.DownloadAsImage}>{t('Download as image')}</Menu.Item>
  </Menu.SubMenu>
)}

The only viz_type-based branching inside that submenu is for "Export to Pivoted .CSV" (Pivot Table only) and, when ALLOW_FULL_CSV_EXPORT is enabled, "Export to full .CSV/Excel" (Table only) [2]. "Download as image" itself has no such branch — it renders unconditionally for every chart type once can_csv is granted.

VIZ_TYPE_DENYLIST in superset/config.py is the only viz-type-scoped control that exists, but it disables creating that chart type entirely, not just its download option [3].

There is ongoing work to add more granular export permissions — can_export_data / can_export_image / can_copy_clipboard behind a GRANULAR_EXPORT_CONTROLS feature flag [4] [5] — but even that splits image export from data export globally, not per chart type. This flag does not appear in the 5.0.0 feature flag list [6], so it has not shipped as part of 5.0.

Bottom line for Superset 5: to disable "Download as image" on Table charts while keeping it enabled on Bar/Line, you'd need a custom frontend patch to SliceHeaderControls that adds a viz_type check around the DownloadAsImage menu item. There's no supported permission, feature flag, or config to do this today.
