BuddyPress.org

Hello, I want to modify two places, but I don’t know and didn’t find where to set up, could anyone help me with this? Thanks so much.

1, when I set up the BuddyPress page, I want to disable the profile sidebar (which was marked 1 in the picture), I just find the Widgets and deleted it, but I want the page to be full width. After I delete the widgets, there is still a blank space in the sidebar. How to disable the sidebar?

2, I want to delete some tabs on the setting profile (which was marked 2 in the picture), I don’t know and didn’t find where to set up, how to delete some tabs there.

Thanks
