The sustain button should not disappear if 'show unused items' is disabled.
This suggests you don't have that control configured properly or are not using the correct on-screen control.
When properly configured, the sustain button will render as a round button with nested concentric circles and will have 'CC 1' watermarked along the bottom.
On the 'Advanced' trigger settings tab, 'MIDI Message' will show 'Control Change'. On the 'Calibration' tab, Min will be 0 and Max will be 7. The polarity is not inverted and the response curve is zero.
These are the DEFAULT settings for a new project. You can create a new project to confirm this and to compare to your own settings. Please double check your settings and that you are correctly identifying 'CC 1' as that is the momentary switch.
Regarding BFD, by default the 'all notes off' (so-called panic) CC message is #123. This is the standard message number for that feature and there is no need to remap it to #64. It's more proper to change the CC number emitted by your momentary switch to be #123.
Personally I don't use 'all notes off' to choke as I don't find that to sound realistic. I instead use the choke articulations for particular cymbals slots. That's a bit more complicated however and involves customizing your keymap, converting CC messages to note on/off and creating a repeater if there is more than one cymbal you intend to make chokeable.
