"Coin control" means manually selecting which inputs to use. Bitcoin Core supports it. Ledger Live doesn't support it, but I can use the same Ledger with Electrum to use it.
In Electrum, click "View" and "Show Addresses" and "Show Coins". That gives you 2 tabs. "Addresses" shows all different addresses, "Coins" shows all inputs on those addresses (an address can have more than one input). Depending on your needs, choose one of those tabs. Then select what you want to use (hold CTRL to select more than one), and use your right mouse to click "Spend frmo" or "Spend".
After this, you can check the inputs under the Send tab. With a right mouse click you can remove certain inputs.

I consider it a good habit to always use coin control. Partially for privacy, but selecting the right input can reduce transaction fees.
