A true nit is automatically worrying about 8x when 3 other players take that flop with his overpair (unless the table is full of nits, which is unlikely.) The board texture is pretty dry too, so he's not going to put people on draws and read their raises / donks as semi-bluffs. This really might be one of those unusual spots where the combination of villain, your hand, board texture, other people in the pot = don't raise flop or turn, lead river small. If the board was wetter, you could try weak leading flop (donk style, to be sure), flat calling his raise, and check-raising the (often blank) turn, but that's not going to work here. True nits are hard to extract from, even under the best of circumstances.
