No need update at all.
Use this trick: for G8.1F
Go to :\My DAZ 3D Library\data\DAZ 3D\Genesis 8\Female 8_1\Morphs\Daz 3D
and same to G8.1M.
Send folders "Base Pose Head" and "Expressions" to zip. Now you can delete these folders or backup them.
Works with all G8.1 like a charm. https://prnt.sc/1qsb84d
