No. No spacers on DS for SRAM cranksets due to machined stop design.
Spacing out DS will hinder bearing from fully seating on the collar. Depending on model RED, if there's no preload adjuster on the NDS, spacers are more functional there. Also you space out the DS, bolt won't catch full thread.
You might want to if chainline is out, or crank too close to chainstay. Just experiment a bit
