I unfortunately moved from one LTS to another, meaning I was in 5.4 before, and this UDP tunnel offloading feature landed in 5.9 as far as I know.

Maybe Jakub can give pointers to specific 5.9 or 5.10 kernel versions I can eventually try, so that I can help refine where this was introduced (or if it was present from the start)?
