Unable to disable client plug-in. The option is grayed out.

Currently running vSphere 6.7 Update 3.  Need to remove client plugin for com.netapp.nvpf.webclient.  After an upgrade the plug-in is pointing to an incorrect url.  The url location is an old external update manager server which was decommed after migrating to the VCSA with embedded VUM.  Removed the extension for com.netapp.nvpf.webclient by going to https://vcenter_server/mob.

But, unable to disable the plugin.  The disable option is grayed out.  What would be the reason for this?

After removing it from the MOB, did you either reboot the vCSA or cycle the vsphere-ui service? If not, do that now and check the MOB again. Does it still show as registered? If it does not, open a browser in incognito/private mode and try again. Does the client plug-in still show?

Rebooted vCenter.  Same issue.
