Here's an option to fix undesired tuning changes when pushing the encoder switch.

Within function read_enc()? which returns the number of encoder ticks that have occurred,
use the Arduino millis() call to determine how long it has been since the non-zero return value.
If there has been a pause in activity of more than 1000ms, then return a result of 0 encoder shaft ticks
but retain an internal copy of the total number of accumulated ticks since the last non-zero return.
When that total number of accumulated ticks exceeds some threshold, then go ahead and
give a non-zero return value, but only return the final encoder read, not the total accumulated ticks.
Giving only the final encoder read value and discarding the accumulated ticks allows me to
advance the knob by just a few hz without overshoot.?

And it doesn't involve any 10 penny nails:
