Disable Import Map Button Within ArcGIS Pro

Question

Is there currently anyway to disable the import map button within ArcGIS Pro?  My organization is about to begin rolling out ArcGIS Pro to all of our ArcMap users.  Our plan is to have those users create new Pro projects that utilize our web services within our Portal, instead of importing their old mxd files that contain layers using SDE connection files to our enterprise geodatabase (which runs within Oracle 12c).  This method would prevent us from having to go back and run a Python script on all of our customers' mxd files to update the data source information after our database accounts passwords are updated.  Are there any registry keys we can set to disable this functionality with the install package we set up for our organization?  If this functionality doesn't exist currently, does anyone know if this might be added in a future release of Pro?  For reference I am currently using ArcGIS Pro 2.5.1.

Thank you for the information.  I'll look into this and see what I can do.

I haven't really compared the two performance wise.  If we move forward with Portal web services in Pro projects, to my understanding we would not have to mess with the Pro projects at all.  Instead all we will have to do is update the registered data stores (within ArcGIS Server) used in each service and restart/republish the service.  Once we do that, all of the Pro projects should pick up the changes, since they would all be using web services as layers instead of SDE direct connections.

Do you find Portal web services to have better performance than SDE direct connections?
