Is it possible to have a broadly invested portfolio, without automatic purchasing of SPCX or AI IPO’s?

Regardless of whether or not owning SPCX is a good financial choice (whether directly or through index funds) I do not want to participate in it because I believe this whole IPO situation is financial fraud and I don’t want to participate.

There exists funds like SPXT, which is the same as SPY, but they exclude all Information Technology companies. This is OK, but a blanket exclusion of an entire sector is a little simple.

Is there some better choice of index that still broadly represents the economy, but not these massive overvalued companies?
