How to change theme for Hugo website hosted on Gitlab

I have generated a Hugo website on Gitlab with Netlify Hugo template. However, I have no idea how to change or replace the theme for the website. I was trying to make it locally and pull first, then push, but it didn’t work. I am still struggling, and try ti find some solution here. Thanks for your time and help!
