Questions about Header For Blog Page

Hi support, I wanted to know if it is possible to have a different header banner image for my blog page. So, I have the header for my website. I love it. But it welcomes the person to my site. Then you can go to my blog or posts page. I would like a different banner if possible. If I can have that, please let me know the instructions to do so. Second, please let me know if it is possible to disable the header on the blog/posts page all together. If so, please send instructions on that as well. Thank you!
