Uniswap V3: how to update local state?

[olegggatttor]

Hi! I need to fetch current state on chain and perform swaps locally (mutable and immutable ones). As I understood, I can perform immutable ones using uniswapV3Math.queryOutputs, but how can I perform mutable ones? uniswapV3Math contains _modifyPosition method, but how can I calculate ModifyPositionParams params for it if I know only params for uniswapV3Math.queryOutputs? Thank you in advance.
