Missing GEOID12B_AK GEOID file for Alaska/United States

I tried to create a compound coordinate system to export data in NAVD88 vertical datum and got the error
"Selected vertical datum is unavailable. Please configure datum transformation."
And that's when I realized that on the geoids page Metashape is missing the
GEOID12B_AK
file from NGS.
Now that I look into it a little more and I see that you're using GTG format, can I just install it myself from the PROJ-data repo
here
?

Hello Andy,
In combination with what planar/projected coordinate systems you would like to use this geoid?
