Razer x not recognized via thunderbolt

I had a egpu setup based on thunderbolt3 and a razer X chroma working on f36 and a t590 lenovo. This setup was working perfectly.
I switched recently to thinkpad x1 extreme gen 4 and f37.
With this configuration the OS does not recognizes (nothing in lspci) the razer chroma devices anymore. When things worked perfectly the razer fans would start as soon as the laptop was turned on at maximum speed and then they would quiet down. Now they don’t even start.
I can’t say if it’s a bios or a OS issue.

some possibly useful information
