AC flush TXV question

[Phillytwotank]

Y’all,
I’m flushing the evaporator. Must the txv be removed.
I have no reason to believe that the TXV is not operating correctly. I did order another one because of an expensive price. But I am concerned about installation challenges, new part quality. Easiest thing for me to do would be to just flush through the hoses, the valve and through the evaporator.
