You can get around the 360 region lock and still buy those games. Buy them on the newer Microsoft Store using store balance gift cards.
Change your One or Series console to the country in question, redeem gift card, add an address to your account in that country and now you can buy the game with the store balance.
Doing this, will usually unlock the games on the older 360 Marketplace as well.
