Change Enfold Basic Layout

Hey There,

I Use Enfold for all my clients, and I love to work with the Avia Builder.
But I dont like the style of the Theme at all. Is it also possible to just use the Avia Builder without all styles that come with uploading the Theme?
I would like to delete all the little rounded corners, delete all the thin lines aroud boxes. I would make everything more minimalist and modern.
I now have to set everything again and again for each customer and adapt it for each newly added module. I don’t always want to write everything in the additional CSS window because the code would then be so blown up.

Do you plan to update the Core style of the Theme or is there any other solution for me to change these things globally?

Thank you!
Monika

Ps: I started to copy paste the additional css. But this does not work every time. Sometimes I use other Plugins (like the Woocommerce shop or Membership Plugins) and then I still have a lot work to do, to change the typical enfold “grid style Design”
