Is there a good list of ways/tricks/systems for minimizing tax impact from a concentrated position?

Curious, since this is seemingly a common problem in tech, when a company goes IPO, suddenly someone has a large amount of their net worth in a single position, but due to high salaries + volume of positions, diversifying causes 50% of that to evaporate if they were to sell.

Is there a good place to read on ways people get around this, if the goal is to stay invested, just diversified?

For example, I am aware of [Exchange Funds](https://advisor.morganstanley.com/the-horizons-group/documents/field/h/ho/horizons-group/Exchange_Funds.pdf), which basically signs a contract to enter some fund by giving your individual stocks for rights to a larger pool of stocks, creating diversification without a sale event. Issue usually is that your stock needs to be part of an exchange fund in order to participate, so options here are limited.

The thread about ["enhanced direct indexing"](https://www.reddit.com/r/investing/comments/1pqoqbb/is_enhanced_direct_indexing_the_right_choice_for/) sparked my interest as well, but seems a little less straight forward since it seems to rely on taking a loan to buy a wide set of stocks via Direct Indexing, and then waiting for some of them to be "losses" that you can sell as you slowly unwind your loans and pull out of your concentrated position.

Does anyone have other sources? [Fidelity's generic article](https://www.fidelity.com/learning-center/wealth-management-insights/diversify-concentrated-positions) seems to not really know of much beyond what we discussed already.
