I think this should be a separate issue, and then ask @MarkRHPearson 

to poke firmware team(s).

Which dock are we talking about? Bugzilla mentions r8152 which isn't to be found in P14s or USB-C mini.

...On the 2nd thought... There might be several revisions of the same dock with different chips.

I don't believe this is something Lenovo can fix the way you suggested.

They aren't even allowed to add a 'boost' switch in BIOS, those CPUs are not

OC approved by AMD.

You are right about overclocking the CPU, however it turns out that the Best Performance power profile in Windows sets higher power and thermal limits than those used in Linux and apparently it is not possible to change them without using third-party tools, which is somewhat disappointing.
