I agree with not 3BETing TT vs an unknown UTG raise. It also doesn't have to be so big, 3x is standard when you have position. He'd likely check this flop with any hand, expecting you to CBET and if he has KQ, AK or KK+ it's easy to just call because the board is very dry. The turn doesn't change anything in this situation so another check call is easy if he expects you to bet. Overall his line is very strong (c/c, c/c, shove) and he's loving his hand. Check behind on the turn and fold the river.
