Changes in post grid in a specific page

Hi,
I am trying to do the following:

I have two different post-grid with the same category: one is shown in the main page and another one in shown in a specific page.

I have no problem with the main page but in the other page, the grid is listed as text (that is what I want) but I need:

- Substitute “read more” for a button
- Increase the spacing between the different posts

The issue is that I need these changes only in that spefic page without changing anything in the main page. Is that possible?

Thanks in advance!
