You can mix human entropy with hardware wallet entropy using a one time passphrase and BIP85

First let your hardware create a new seed normally. Enable passphrase. Use the passphrase field to enter over 100 dice rolls or any other equivalent entropy and apply. Do not worry about remembering the passphrase. After passphrase is active select BIP85 seed and copy the new BIP85 seed.

Only keep the final seed and throw out the dice rolls or passphrase info and original seed (only if empty). Your final seed will be created using hardware entropy in original seed and human entropy from the passphrase. If either make a mistake in entropy the entropy is still good and requires failures of both to fail.

Works on hardware wallets that will support BIP85 after passphrase
