Anyone here have experience of Debian on Thinkpad P series?

I'm thinking of getting a refurbished Thinkpad P Series laptop to
replace my existing Thinkpad T470.  I want a larger screen as my eyes
are getting older.  Weight and size isn't a **huge** issue but I don't
want anything a lot bigger.

So, something like a P1 gen 4 would seem to fit my requirements but
I'm a little wary of them nearly always having dual display hardware,
Intel 'built-in' and Nvidia.

Does anyone here have experience of installing Debian on one of these
systems with Intel and Nvidia?

Although in theory there should be Thinkpad P series with no Nvidia
hardware (it is an option) I have yet to actually find one for sale.
