It is possible to have different headers for the different pages of your website. You can choose a particular header to display on the homepage, and then another to display on blog pages. In this way, you can achieve your requirement of having different logos on different pages.

Astra provides two features (exclusive to Pro users) which you can read about here: https://wpastra.com/docs/different-headers-on-different-pages/

I hope this helps you!
