I would like to ask if there is any way to convert WHMCS to money as an integer

I would like to ask if there is any way to adjust WHMCS to integer money, because my country uses 33,333 VND, not 33,333.33 of WHMCS, so the auto system cannot automatically approve

The first photo is the form of WHMCS, photo 2 is the photo shown when the customer needs to transfer money, but when the amount of money transferred is correct, the auto system does not approve, my auto system still works normally
