Stephen,

Check the minimum equipment list in the flight manual, and the FAA Type Certificate Data Sheet. If it's not listed there, then there should not be a requirement to have it installed.

I can't find a TCDS for the Russia, so it must be experimental only, that should make it even easier to do without the ballistic system.
