A long cage Force/Rival 11 speed can do up to 46. I use an 11-46 with Force RD on my cross bike, and a 9-46 with Rival RD on my gravel/rigid MTB.
Edit: realizing you mean 12-speed. I do wish they had made a long cage version of Force AXS but I guess that’s what Eagle AXS is for, with the benefit of getting away from the flat top chain.
