Try to disable other plugins for debugging purpose to isolate the possible conflict.

You can use following custom css

.buddypress-wrap .standard-form .field-visibility-settings-header {
display: none;
}

@lunarayven You can check following codes and use them with Snippet plugin

Change “Activity” component’s name and slug to something else.

Other references of “activity” string at the frontend can be translated using Loco Translate
