I know that the current MBP can power 2 XDRs. But can it do a third if I hook up a BlackMagic eGPU with it?

Probably only if you are going to do 2 XDR's off of the eGPU, but that's a guess. I don't think you're imagining a very common use case scenario. ?

EDIT: I'm not even sure the BlackMagic eGPU's out there can even drive two XDR's, I'd start the research there first.

Not that I doubt you want/need three such displays, I'm just curious as to what you do that you could make use of three of them.

Yes, an eGPU should get you another Pro Display XDR.

Obviously no one here has had the money to buy that config. But that setup normally works great to extend the supported monitor count.

Blackmagic eGPU only has one downstream Thunderbolt port, zero or one DisplayPort port, and does not support Display Stream Compression (DSC), so it can only connect one XDR display at 6K (because two DisplayPort connections are required for 6K when there is no DSC).
