I have “Main Navigation Block Style” set to yes, but I only need this on the homepage. What is the best way to have non-block style menu for all the other pages?

As this is not an option at the moment you could modify your header.php template in your Child theme and add a check in it to where the “block_header” class is added.
Currently there’s a check there for the option being set:

echo (boc_is_main_nav_block_style() ? 'block_header' : '');

you could modify this to also check for the static home page:

echo ((boc_is_main_nav_block_style() && is_front_page() )? 'block_header' : '');
