Looks like a mis-genotype by Onso in HG002 as homozygous, since for some reason (maybe unlikely random sampling?) only 1/20 onso reads in HG2 supports the ref allele, even though ~50% of reads in Element and HiFi support ref

I agree with @jzook here. The T->C variant appears to be a misgenotype in HG002 called as HOMVAR, but it is most likely HET. Some additional evidence that it is HET is that the neighboring phased variants (two base insertion and G->C SNP) also appear to be HET.
