How to remove the true type instruction?

I got this problem when I was exporting the VF. Could you tell me how to remove the TrueType instructions?

When you open a compiled TTF, Glyphs stores existing binary instructions in the custom parameters in File > Font Info.

Better to work with the actual source files, not the TTF.

Thank you, That helps a lot.
