How to unstake some funds from staked balance from validator?

I have a validator pool setup using coincashew guide. I want to remove some funds(not all) from the staked fund. Which commands do I have to follow? Thanks.

What exactly do you want to do:

  1. Move some ADA from that wallet?
  2. Reduce the pledge amount?
  3. Both 1 and 2?

Yes, I want to reduce the pledge amount and transfer that amount to another address. I do not use wallet I did set up on a terminal with key files using Cardano: ADA - CoinCashew this guide.
