Do you mean that you can't use Blake3 in Virtualbox? That would be odd, because Blake3 only uses AVX2 if the processor reports that it's available.
It means AVX2 could not be used in hash calculations, and tests show that SSE2 implementation is over 4 times slower.
Cryptogrhapic hash is an onverkill for basic data verification; maybe even simple checksum using combination of rotate and xor might be good enough to catch disk or memory errors. Archivers keep using CRC32 and nobody is afraid of large file sizes.
Or take a look at xxHash for fast non-cryptographic hashing.
