RTC setup wih cell coin in Jetson Nano Developer Kit 945-13450-0000-100

Hello, checking the schematics found in the following LINK I realized that there is a gap for a Schottky diode (D64) in the coin cell Ve line (BBAT_CONN) (see attached pictures).

Should I attach a Schottky diode in D64? Can you recommend me which one?
