Vsphere 6.7 disable plugin (NetApp Virtual Storage Console)

I have inherited a VMWare installation that has an old version of the NetApp virtual storage console installed (it actually claims to be a "HTML5 technical preview, only for lab environment" when opening the overview).

This plugin doesn’t appear to work and we’ve been told by the NetApp hardware support company that it’s likely because of version incompatibilities (I assume VMWare/NetApp has been upgraded over the years and this plugin has at some point stopped working).

However, every now and then I get NetApp Create Backup tasks that start up before failing at 69% and sitting there doing nothing until we fully reset everything (As is the case with 90% of VMware tasks, you can’t actually cancel it). It also creates a bunch of svmi snapshots that have to be cleared manually. We were told this is probably being initiated by software somewhere, but I’m starting to suspect this plugin as the documentation suggests it has a scheduled backup feature (https://library.netapp.com/ecmdocs/ECMP12412052/html/GUID-3524608B-3A8A-4127-8528-6D99A4E2206F.html).

Looking in VMWare documentation, I should apparently be able to go into Administration -> Client Plugins and disable the plugin. However, I don’t get any options to do anything on this screen. Just a list (right clicking on any plugin also just brings up my standard browser menu)

The only other option I can find is using the java object browser on the vcenter server, but there are several netapp classes and I can see that ending in a broken vcenter server giving me scary errors about missing classes.

Does anyone have any further insight into how I can get this plugin disabled, or maybe just disable this backup job or confirm what’s starting it.
