For reference: The last serious match between the top human player and an engine was Brains in Bahrain, Kramnik–Fritz 7, in 2002 (already that should tell you something). Well, actually a broken and buggy version of Fritz 7, but that's another story. It was a 4–4 tie. On the latest CCRL list, Stockfish 18 outranks Fritz 8 (the oldest Fritz version on the list) by 947 Elo points _on the same hardware_. (For comparison, Magnus Carlsen's peak rating is 65 points higher than Kramnik's peak rating.)

Add to that 24 years of hardware development, and you can imagine why no human player is particularly interested in playing full-strength engines in a non-odds match anymore. Even more so in FRC/Chess960 where you have absolutely zero chance of leading the game into some sort of super-drawish opening to try to hold on to half a point now and then.
