How to expand memory usage for Create Full Rig?

Summary

I get a “requires 10GiB free memory but only 6.7GiB is available” message when attempting to Create Full Rig on an MH (testing Aera preset). PC has 11GB Free on GPU and 21GB Free in RAM but UE/MHC doesn’t seem to be grabbing it. How can this be addressed? (system has 24GB total on GPU / 64GB total in RAM)
