AUFS is not supported over aufs on berryboot RPI3

I was trying to install Docker-CE onto a Raspberry Pi 3 running Raspbian 10 via berryboot, but it fails to start with the following:

AUFS is not supported over aufs storage-driver=aufs
‘overlay2’ is not supported over aufs storage-driver=overlay2
‘overlay’ is not supported over aufs storage-driver=overlay

My / partition is indeed mounted via aufs, so I’m assuming Docker doesn’t like that. Is there any way around this? I’m running the Berryboot so I can take advantage of my WD Berrydrive.

Thanks
