    Looking into the situation, I've found that there isn't a built-in
    collision avoidance value but rather a well-tuned set of spacing
    parameters (unless an actual beam exists, then collisions are taken
    care of). It's quite easy to have the tremolo flags of unbeamed
    stems cause collisions with the notehead:
    
    \override
        Voice.StemTremolo.length-fraction = #1.5

    Here's another option that works nicely by adjusting the value for
    "pad":
    
    \layout {
        \override Voice.StemTremolo.after-line-breaking = 
        #(lambda (grob) 
          (let* ((pad 1.0) % <---
        ADJUST THIS TO TASTE
                 (cnt (ly:grob-property grob 'flag-count))
                 (stem (ly:grob-object grob 'stem))
                 (leng (ly:grob-property stem 'length)))
            (if (> cnt 2)
              (ly:grob-set-property! stem 'length (+ leng
        pad)))))
      }
