I’m looking for game variations with Surrender option. Any live casino software providers offering this?

Yes. Ezugi have live blackjack with an early surrender (meaning dealer does not peak for blackjack on tens).

Visionary iGaming offer live blackjack with late surrender where dealer first peaks for blackjack and only then you are allowed to surrender.

Unique Casino is a good site to enjoy live blackjack with surrender option at.
