No it is bumper off.
You might be able to get to the drivers side with an extension to socket wrench with 10mm socket but passenger side is blocked by the air box.
It's an easy job to get the bumper off anyway, takes 10-15 mins, just watch out for the two 10mm bolts either side of the centre as they can shear, lots of plusgas should solve it.
The rest are easy but be careful with the arch trims as there are some delicate tabs, one with screw, one with plastic clip.
