Can you backup Time Machine on MULTIPLE external drives using APFS?

I just upgraded from Catalina to BigSur. On Catalina, I was Time Machine backing up to two separate external drives formatted as HFS+ encrypted.

My question: If I want to move to APFS encrypted drives for Time Machine backups, can I back up to TWO separate external drives? Or does the new APFS Time Machine format only allow backup to one external drive?
