Is there any way to override or hide the standard "Import" list view button in Lightning?

Question

In Lightning, the Recently Viewed list view for a custom object has New and Import buttons by default:

I would like to override or hide the Import button since our custom object has a custom import process.

The override works fine for the New button as explained here: https://help.salesforce.com/articleView?id=assign_action_overrides.htm&type=5

But the same process doesn't work for the Import button due to the following:

• Import does not appear in the list of actions
  I was able to get around that by hacking the Setup URL (edit the New action and replace New by Import in the URL)
• The editor only shows the Classic override option
  Not the Lightning and Mobile ones available for the New action
• But most importantly, the Classic override does not work
  Nothing happens when I click the modified Import button. So at least it disables the default behavior -- which is something I guess -- but I would really like to attach my own. Even when I select the exact same Visualforce page that I use successfully for the New button nothing happens when it Import is clicked. Nothing in the log either

Any tips would be much appreciated!

Answer 1

I don't think that Import Button can be disabled from Lightning Page layout. You can achieve this by revoking permission for particular user on concerned object.

Answer 2

There is an import permission: https://help.salesforce.com/s/articleView?id=000352015&type=1
