There is an established mechanism for doing this called selling shares into the secondary market. From Carta:
Between 2012 and 2021, the global market for venture secondary deals grew from $13 billion to $60 billion. This growth happened in part because the primary market for venture capital also grew: Over the same span, annual global venture investment rose from just over $50 billion to well north of $600 billion. This growth culminated in a record-setting 2021.
[Added 17Nov: the selling of private equity, e.g. in FTX, on the secondary market seems like it was quite possible in 2021. It is a tragedy that this wasn’t done.]
