All of the AMD SVM cores supported real mode in guests as far as I know, and Sandy Bridge is a decade old at this point. But yeah, that was really annoying, retconned "restricted guest" would happily let you put real mode segment info into the VMCS, but just silently would be broken in goofy ways. I tore my hair out for a while writing a hypervisor back then that was intending on running some real mode code until I figured out what was going on.
