When can we get Mac OS Big Sur on the iPad Pro 2021

Apple has never said anything about porting MacOS to the M1 powered iPads. So unless some day they announce something about any such plans it appears that all iPhones will run iOS, all iPads will run iPadOS and only Macs will run MacOS.

Anything else is just rumor or speculation.

You won't. It's for Macs, not iOS devices,
