Intel seemed to fall behind kinda hard w/ regards to CPU/Motherboard features until much later on. Supposing you aren’t working with parts you already have, everything from 1st generation Ryzen onwards would have rebar support. They can be had very cheaply too, and work on any AM4 board.
You may also find a BIOS update allows some older chipsets to support rebar. It’s a tad flaky depending on the manufacturer though.
