Interpolating data merge Rotation?

any way to interpolate the change in rotation for display entities? - or an alternative to data merge Rotation? currently I'm rotating it by translating and modifying its Rotation nbt I also tried my luck with teleporting it, and it worked but I couldn't figure out how to strap it to a player and I would prefer for it to change without lagging behind anyways And is there a way to disable the automatic rotation when teleporting a display entity to a player?
