Do you have a discrete GPU? Disable it. Run TLP and powertop to see what uses too much power and to adjust tweakables.

I do not have a discrete GPU, have run TLP and Powertop and have adjusted the tweakables. Maybe it's my 1440p display.

If you use zenmonitor, what is the package power on a typical workload? It should be 2-3W maximum normally. If it's too high, it's a too common case of manufacturers setting insane tweakables, and can be remediated using amdctl/ryzenadj/zenstates (or in some BIOSes using the PBO2 setting). Otherwise, it can sometimes be a bad SSD using a lot of power.
