How to remove the border of the current area block?

[Faputa]

It is a great plugin, but I would like to remove the border as it looks ugly.

Alternatively, I believe that indicating the current scope of the request in the editor by using a vertical line on the far left would suffice.

set httpyac.useDecorationProvider to false

I will not change anything in the current state at the moment. I like your suggestion, but I also like the approach where I imitate the cells from vscode notebook. The easiest way is to deactivate the decorations with httpyac.useDecorationProvider=false in the settings.
Alternatively, it is also possible to customize the decorations by passing your own configuration for the httpyac.decorationActiveRegion and httpyac.decorationInactiveRegion settings (see VSCode DecorationOptions).
