Now I just have to figure out how to get Dell SupportAssist to stop trying to re-install an update for the SupportAssist OS Recovery Tools v5.4.1.14954 that it already installed back on 13-Apr-2021 (but that's a problem for another day).

If I recall correctly, disabling System Repair in the Dell SupportAssist settings achieves the same thing because it automatically disables the Dell SupportAssist Remediation service. The only difference is that you will see the warning "When System Repair is turned off, we'll remove any backups we created for you and free up any hard drive space that they used. You can turn System Repair back on at any time if you'd like to back up important system files again." when you disable the System Repair setting in DSA (see my image ). After turning off System Repair I could still see older backup files at C:\ProgramData\Dell\SARemediation\SystemRepair\ when I viewed this hidden folder with TreeSize Free so I'm not sure that warning is actually valid, but if loosing your old DSA System Repair restore points is a concern it's probably better to just disable the Dell SupportAssist Remediation service manually and leave System Repair enabled to see what effect that has on your own system.
