DSI interface on Rock5c - Tearing effect

Does Rock5c support tearing effect with its DSI port? I plan to connect a 39 pins DSI display to Rock5c but I stumbled across the tearing effect pin (pin 31 TE Tearing effect signal to frame memory writing)

The LCD panel also uses 1.8v for both panel reset and touch panel reset while Rock5c’s reset pins are 3.3v, so I expect to have a logic shifter 3.3v - 1.8v?
