Congratulations on having chosen your notebook well! Too few notebooks are designed that well as to noise.
Since I started looking (RTX 3000 launch time), I have not seen a dGPU notebook convincing me. Individual aspects meeting my wishes have been met (reasonable noise, all keys mechanical, keyboard layout etc.) but not in combination. Note that heat does not imply loudness ALA combined TDP is within limits, but demands a very good cooling solution.
As to a firm (wobble-free) mechanical keyboard, the other essential aspect is a good layout (essentially German, esp. ordinarily sized arrow and numpad keys, four page navigation keys, no nonsense aka fused keys / illogical grouping). I prefer deeper key travel bit can tolerate medium travel. Otherwise, I have few keyboard requirements because I need none of the gaming gimmicks; I am already happy if any lighting can be deactivated. Key noise I do not care because it does not annoy me or others nearby and, unlike fan noise, is not permanent. Dust protection and a medium to large width of the left Shift key despite otherwise German I can appreciate though but I can tolerate either missing if only cleaning is possible.
