Fees staking ETH on ledger?

Hello to all,

I would like to start staking ETH on ledger with LIDO.

My question is, Do I have to pay fees every time I want to stack a certain amount?

I am asking this because if I do DCA every single time that I buy i would like to stake… but If I have to pay fees then I have to think about a staking strategy.

Thank you.
