Hi Eduardo,
Thank you for reaching out to us. 🙂
Indeed, it is possible. I can explain you how to do it, but it will depend of what exactly you want to do. To do so, you’ll need to add a block/widget in the After Content, a widgets zone created by our theme.
Please click on Customize > Widgets > After Content.
A banner without carousel:
We suggest you to use Grimlock section. This widget has been developed by us and gives you awesome possibilities of customization. Please find the attached screenshot as an exemple of what you can do with Grimlock section.
A banner with carousel:
Since WordPress 5.8, you have the possibilities to add Gutenberg block on widgets zone. You just have to install a banner plugin that include slider and add this block in the After Content zone.
Let me know if you need more explanations. 🙂
Best,
