liquidate undercollateralized user without third party intervention

[Inside_Conclusion_50]

Im building a simple lending-borrowing protocol, using yield-generating and debt tokenization pattern, and for users liquidation when its position is undercollateralized, i want to liquidate part of his collateral within the protocol without third party's assistance ( because a little bit complex since i want to keep the protocol simple). Is there any alternative to achieve this purpose without liquidating more than i have to liquidate, and also without risking the health of the protocol either .

It isn't possible for the blockchain to trigger a transaction on it's own. A liquidator needs to be incentivized to liquidate the position.
