A cautionary note:
At around your stage of flying, boredom or a need for further experiences sets in. A quick bit of IMC and "following the needles" seems like a good solution.
The commonest cause of a fatal GA crash in N America is unplanned flight into IMC. Whilst most of the pilots who end up in smoking holes are non-Instrument Rated, an embarrassingly large number have (had) an IR but their excursion into IMC was UNPLANNED. It bit them and their passengers.
If you want to fly an ILS then plan it before. That means instruction +\- Instrument Rating yourself. As mentioned above, a quick demonstration of "the leans" or other kinesthetic aberrations should show you what IMC can be like. If you don't think this through and plan, then statistically you're likely to shorten your flying career.
I'm sorry if you didn't want to hear this, but superior airmanship and sensible decision making will go a long way to keep you from having to use your (?superior) MSFS skills.
Keep safe
