Copying my comment over from fmhy instance -
If you don't mind paying ~2$ a month, you can get Family Premium using a VPN (I used India)
Current working method from HUKD: (Private/Incognito browser is best)
Create a new Google Account. Enter card details. Enter a fake billing address, any random address generator will do, as long as it’s from the correct region. Then select Try it Free. Navigate to YouTube, press YouTube Premium, and double-check that everything is in the right currency. Enter the same credit card and address information you used for creating the new Google Account. Click Buy 👍
You can then add your main Google account as a family member.👍
