Avoid fast track IPO’s while keeping broad passive strategy?

There’s been a lot of chatter around indexes changing their rules to allow inclusion of new ipos for Space X (which will ipo around 2T making its s&p representation near 10%) and OpenAI. I don’t have an issue with the weighting or price specifically but the fast tracking without time for market price discovery is problematic for me. In my opinion this is essentially the current owners getting a free pass to time the market at all of our expense. Is there a feasible tactic to avoid the ipo period (say 6-12 months) while maintaining broad us equity exposure passively? I’m a passive investor with \~75% in VTI so I don’t want to do anything complex but if there’s a variant which is a similar index without being forced to be a source of liquidity for venture funds at the time of their choosing I would like to consider that option.
