Permalinks without post type

I use norebo theme

I use it when I open a Portfolio the link is in this format

https://www.hshnorm.com/project/fruit-flavored-powder-juice/

How can I remove the word project

To be the link in this format

https://www.hshnorm.com/fruit-flavored-powder-juice/

is project a custom post type?
if so, it’s been answered here Custom Post Type URL Rewriting?

but, if that is a regular post, it would be in the Settings > Permalinks to set the permalinks.
