Hello @alize,

Currently, there is no option in the theme where you can manage the setting of header image in each page but you can use the CSS targeting the ID of the page and remove the header image.

For example add below given CSS by going to Admin Panel > Appearance > Customize > Additional CSS.

.page-id-1788 div#page-site-header {
    display: none;
}

Here replace the iD with your page ID.

You can find the ID in individual page edit screen URL.

As for the Top header menu just go to Admin Panel > Appearance > Customize > Menus > Menu Location and do not assign any menu on the “Top” Menu Location

Hope this helps.

Let us know if you have any confusion further.

Best Regards!!
