I am deploying with usb://ledger using anchor deploy

It shows a different output than when using a json wallet.

Deploying workspace: https://api.mainnet-beta.solana.com
Upgrade authority: usb://ledger
Deploying program "lpfi-buyback-program"...
Program path: /Users/aperire0402/lpfi-buyback-program/target/deploy/lpfi_buyback_program.so...
Waiting for your approval on Ledger hardware wallet usb://ledger/7KDQhb9KX8y9rkrtyAw4arkRVctGhaRhaUMCadfg4bEk

The program is small, but I am clicking my ledger button over 100 times. Here is the tx when I started the command. https://solscan.io/tx/3yV4nhv1FUwUyzkLB8c3xo611P2MFcBmhoEJkMsyZ5pXoEbKQouXmscHZBF9dWSaDU8gtvuHzT7LJzEgu4HV9A9x

You can deploy a program using regular key and then change program upgrade authority with solana program set-upgrade-authority

If you want to deploy a program controlled by a Ledger, your best option is to do the deployment normally, then change the upgrade authority to the ledger, as recommended by the ASkibin's answer.

Whenever you want to upgrade, however, you'll need to use an intermediary buffer account, doing the following:

solana program write-buffer <PROGRAM_SO_FILEPATH>
> get BUFFER_ADDRESS from this command

solana program set-buffer-authority <BUFFER_ADDRESS> --new-buffer-authority <LEDGER_PUBKEY>
solana program deploy --program-id <PROGRAM_ADDRESS> --buffer <BUFFER_ADDRESS> --upgrade-authority <LEDGER_PUBKEY>

You can find more information at https://docs.solana.com/cli/deploy-a-program#using-an-intermediary-buffer-account
