Will my KYC exchange account get restricted if I sell my crypto on XMR-listing, non-kyc exchange like Trocador for let’s say ETH and send it to my KYC exchange account?

No, you can of course read the terms and conditions, but the simple answer is that the KYC exchange cannot see this at all. The best thing to do is to first send the amount for the sale from your normal wallet to a newly created wallet and from there to the instant exchange after a certain amount of time. So take an intermediate step, an additional new wallet.
