I used a saber saw. I bought a cheap chainring that was a lot cheaper than a chainguard ring. Cut the teeth off with a saber saw. That of course left a rough cut. Put the ring on the crank arm and hand turned the crank for about 10 or maybe 15 minutes while I held a file on the rough cut until it was quite smooth.

Saber saw, I used a fine tooth metal blade, the aluminum clogged up the teeth, I might have used two blades. But I had plenty of blades so that was not a problem.

Aluminum is not that heavy, works well for me.

Photo is old, later I decided to spray it black to match all the other black stuff. This is obviously not a folder. The chainring I cut was a 52T, the chainring behind it in the inner position on the double crank is a 44T. The guard is a bit bigger than ideal, but it is close enough that I have no desire to replace it.
