Hi,

Probably. Among the automatic grub-mkrescue options for xorriso's mkisofs
emulation is

  --modification-date=3D2019042117165600

The equivalent native command is

  -volume_date uuid 2019042117165600

So you indeed have to override this by an own subsequent command.

(SOURCE_DATE_EPOCH overrides defaults of xorriso. But commands or options
 override the overridden defaults.)


Have a nice day :)
