For boards that don't have a single "TDP" setting, then set 88W PPT, 60A TDC, 90A EDC to limit it to the same as any Am4 65W TDP chip. This only slows my 5800X chips in my home servers by 8%. Instead of something taking 10 seconds to complete, it would complete in 9.2 seconds - not a huge difference. A Negative 20 curve optimizer value brings the performance back, and has been solid on my chips. -30 would generate an error about once a week, but was stable in various load tests for days. I run three 5800X chips, and two 9600X chips in my systems.
My 9600X chips can do an incredible -39 CO stable in various stress tests, so I run them at -30. 40% faster per core than the 5800X, and 20% faster all-core.
You can also do this by simple setting 1 value in just about any motherboard's UEFI.

Or you can use AMD's Ryzen Master to enable eco mode, not sure if there's any difference. When I loaded up ryzen master for the first time it already shows me being in eco @ 65w so it probably communicates with the BIOS somehow.

The $80 5500X even seems like a better price. You only get two more cores (133%) with the 5800X for 225% of the price.
