This is beyond hospital IT control. Clownstrike (sorry, Crowdstrike) unconditionally force-updates the hosts.

Likely because staggered updates would harm their overall security services. I'm guessing these software offer telemetry that gets shared across their clientele, so that gets hampered if you have a thousand different software versions.
