Running exome burden test

I am in urgent need to run rare variant burden test on GRCh38 exomes
I found, that it is possible to use gnomAD cloud services instead of downloading entire file

I only found GRCh37 exome files. I can lift over them, but to my knowledge, liftover is not the best option

Therefore the question:is that possible to run rare variant test on GRCh38 exome VCFs, using gnomAD v.3.1 genomes as controls?

Thank you!
