The solution is to fix your internal audit. There's fundamentally no
way to hide the source code, and it's going to add complexity.
Demonstrate that it could take you a large number of man-hours and
achieve little, and just declare that the source code IS what you
want.

Alternatively, you could do a source-level reformat that crunches
everything down as much as possible, while still producing
syntactically-identical source code. Remove all the comments, shorten
local names to one letter, etc. That would result in something that,
while still perfectly executable, won't be nearly as helpful. It
wouldn't be nice readable source code, at least. Would your audit be
satisfied with that?
