Not quite what OP's looking for, regardless.

As far as I can tell, *all* x570 boards are limited to x16 to the 'cpu-connected slot(s)'. They are bifurcatable, but limited to x16 being allotted.
x4 go to the X570 Chipset, and I believe the other x4 are used for primary on-board devices (USB, etc.).
tl;dr: You're not going to find an X570 board w/ >x16 lanes off the CPU, accessible.

Without going into custom mountings and assortments of risers, you're stuck w/ x8/x8 (maybe, x12/x4), etc.

Theres only about maybe 10 or less boards that actually do 8x/8x for the x570, the rest all do 16x/4x

wow dam, thats sucks. I hadnt realized that. looking back on older cpu has it always been this way?

what about those who did sli or tri sli? they were running 16/4/4 ? that doesnt sound right...

Theres only five S.L.I certified boards for the x570 on AM4. I have on in my systems it's the MSI MEG ACE x570.
I think the x470 had more slightly more.
The TRX40/WRX80 & both the newer workstation/HEDT boards that use RDDR5 TRX50 & WRX90 still have support for S.L.I.
People don't even know that all of AMD's RDNA GPU's from the 5,000 series to the 7,000 series can run mGPU in dual card mode. ¯\_(ツ)_/¯
It's listed in almost every manual that is says it support AMD multi-GPU setup usually still even today.

why are these cpu limited this way? no matter if its a 5600x or 5950x, only 24 lanes?

Because both uses the same IO die.

Way back then we have chips like nvidia NF200 that have 32 lanes for SLI/Quad SLI but since that no longer a 'thing' people no longer use them.
