Did you set the update deadline for Office?
According to the article "End-user update notifications for Microsoft 365 Apps", the Hide update notifications setting doesn't hide notifications related to deadlines.
Please also go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Updates
, check the values of "UpdatesBlockedTime" and "UpdatesReadyToApply" are 0.
(Serious problems might occur if you modify the registry incorrectly. Before you modify it, please back up the registry for restoration in case problems occur.)
Any updates, please let me know.
