How can I adjust Touch Bar brightness?

Is there a way to adjust MacBook Pro's Touch Bar brightness?

MacBook Pro, 13", 2016, macOS Sierra 10.12.6

Solution 1:

You can't. It may automatically adjust based on external lighting conditions if the "Adjust keyboard brightness in low light" option is on in System Preferences>Keyboard, but I haven't experimented to confirm this.

Solution 2:

You can put a small sticker, or something similar, over the ambient light sensor on a Touch Bar equipped Mac to set the brightness to its lowest setting.

Note that the ambient light sensor is the smaller circle beside the camera's circle. You can test it out by putting your finger over just the smaller circle and noticing the Touch Bar's brightness reduce.
