The DP4 part spells out how many reads aligned to reference and alternate allele. So you can parse based on that. You could do that with some finagling in Excel, if you had to.

How to filter out SNPs with Minor allele frequency less than 5% in VCF file
Hello,
I would like to filter out SNPs with allele frequencies in VCF file from multi-sample variant calling.
I tried VCFtools with the following commands, but it doesn't work.
vcftools --vcf input.vcf --recode --recode-INFO-all --stdout --maf 0.05 --max-maf 1 --out outpur.vcf

Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...-
