2021 M1 Pro MBP 14" External Displays Question

Is it possible to use a Thunderbolt dock to power a 24" 1080p display @ 60Hz and a 27" 4K display @ variable Hz (144Hz)?

Or do I have to attach the two displays separately to the Thunderbolt port? I'm thinking of buying a Acer XV275K monitor to do a dual screen setup with my existing 24" Dell monitor and been wondering if it would even be feasible with the M1 Pro.

The technical specifications of only being able to power a 60Hz display via Thunderbolt doesn't seem to be in alignment with what I'm reading online. But it seems like I'm getting the different iterations of the Apple silicon Macbook Pros mixed up.
