 S199pWa1k9r/quartz64_uefi is based on jaredmcneill/quartz64,
modifications for R5S may:

 I dd'ed NANOPI-R5S_EFI.img to SD card, gpt destroy, create
then add loder,uboot,env and netbsd-root partions, that boots good.
cool. greate.

 Two reminders. Serial console might be mandatory.
Soldering 3pin header to "Debug UART". In FriendlyElec's page
say 1500000(1.5M)bps, but I could see output from UEFI and
NetBSD when 115200bps.
