Hi: When you deactivate someone, that information becomes available throughout the system. Blocking the updates on My profile is going to hide a portion of the many ways people will know. How about trying this? Instead of deactivating them, first disable their account: Remove their ability to log in, give them a bogus email address (I append _NO to their email address), or give them a bogus SSO ID (I append _NO to their SSO ID); Remove their visibility into things by assigning them to a "Pre-Deactivate Group" and a "Pre-Deactivate Team". Remove all other group and team memberships; Then, when it can be announced, deactivate them. I bet others on the forum can come up with things to add to the list, above. Thanks,
