Avast Business Autoupdate Fequency

I am in the process of moving from Avast Endpoint to Avast business. I selected auto update for definitions, but I didn’t like that it was set to 4 hours by default. I can see in the individual clients it is set to 240 minutes and I can change it but it reverts back on reboot to 240. I see no options in the console (on premise) to change it.

I really didn’t want to create 24 tasks so I can check every hour, but I don’t see any other option. Am I missing something? Also, why put an option on the client that can’t be changed?
