Is there a more privacy friendly way to achieve changing public keys then sharing your xpub?

Example:

I am buying Bitcoin from a broker and instead of changing my BTC address everytime, I would like to have it automatically pick a new one each time. I have seen some brokers accept xpub, but this means they know ALL of my pub keys which is a privacy problem imo.

Ideal would be something like a partial xpub, where I can decide how many pub keys are being shared.
