If you can't find any services that takes your btc without doing any KYC, you can try bitrefill.
https://www.bitrefill.com/Bitrefill is a giftcard provider which takes your crypto and doesn't require you do any KYC. Since we almost always top our mobile phone or buy stuff from amazon and similar retailers, getting giftcards are almost as good as having FIAT. Their margin is like 10% on the product I am looking at right now. It is not the lowest but it is better than nothing I guess. Maybe use it as a temporary solution till you find a better deal.
