How to disable Save-As button on Read-Only office files

Hi Everyone,

I am configuring SharePoint Online for my organisation and received a request that whether we can disable the "Save As" button on the Read-Only office files (excel, word, etc.).

The image attached showed the case when read-only users modified the file and then try to save it but as they do not have the permission, the "AUTOSAVE FAILED" notification will pop-up.
