Yes. Mammoth sells the "click less bypass" which does this. Check the instruction sheet for how to do it on Boss pedals specifically.

to get untainted sound when the effect is bypassed, guitarists like true bypass switching. One way to get this simply is to make a true bypass box external to the effect, and just use short cords to connect the original effect up to it. If you are dexterous and can mechanically get a DPDT stomp switch inside the TS box, you can convert it to true bypass. This conversion is simple in concept. The two switch JFETs are pulled off the circuit board. The one from the input buffer is ignored, the drain and souce holes for the one at the volume control are shorted with bit of wire. This disables the electronic switching and makes it permanently "on". Then the external DPDT switch is wired for true bypass around the whole mess
