How can I customize my Dawn Theme featured collections without price tags?

How do I edit multiple featured collections so that I remove the price tags, center the subheading text, center and custom edit the title, and add a drop-down feature? I know that is a lot but I have so many issues with my featured collections on a certain page. I am an artist. I would like my gallery to be filled with a display of my art and I have a separate page where I will sell it.

This is what my gallery currently looks like:

Here is a photoshopped mock-up of what I would like it to look like:

The drop-down feature is important to me because I have a huge variety of art. I also have a lot of collections. I would like to be able to keep it concise and have the viewers push the drop-down if they are interested in a certain collection.

like I said, previously, I would only like to edit all of these features on this page because I would like to be able to sell my art on a separate page. So I definitely need the price tags on my other collections but I would just like them removed off of these collections.

If figured out the drop-down, centering the heading and description. Now all I need help with is removing only the price tags from this specific page. Like I said previously, I need the price tags in other locations of my store. I’m using the same template for all of my gallery collections which happens to be different from the default template for my other collections. Is there anything I can do to edit the code to remove the price tags from just this page’s collection template?
