Drywall is off, can this wall come out?
Based on the current very top picture there are three main indicators.
#1 - These are directly under and perpendicular to the loaded joists.
#2 - As mentioned in the comments the left part of the wall is under the footings for the truss.
#3 - This is actually the most damning evidence of this being load bearing...   The right side of the picture.   Two clues here - the brace for the plumbing and the wall of 2x4s.   You simply wouldn't worry about a plumbing brace on a non-load bearing wall and you definitely wouldn't squeeze 6-7 2xs at the end of this wall (also a good indicator that this is a point load and the door and over to the right are not of consequence).
Again if you are set on removing you can consult and engineer/architect with full blueprints.   I mean normally you don't need this many load bearing walls in a short span so maybe there is a solution but no inspector will allow you to remove it without sign-off.
