Firewall SFOS v21 update with Central?

Hello,

we would like to update SFOS/XGS appliances of our customers to v21 with central.

We have to use central because there is no other way to do this scheduled at night. Version 21 GA was 17.10.2024 and the update is still not possible to do with central? Really?

How to handle security updates / critical CVEs if you have to wait weeks to do that scheduled with central for all your customers?

regards
