When you go to Seller Admin > Pay Your Affiliates every month to obtain the masspay.txt file we provide to pay your affiliates for the last completed month's commission earnings, you can open that masspay file in any plaintext editor like Notepad or TextEdit, note the earnings for that affiliate who doesn't want PayPal, and delete their line from the file before you upload it to PayPal Mass Payments. Then you can pay that affiliate separately by whatever means you wish.
