Hardware wallets are a good tool for newbies, I have been explaining them differently now, they are a signing helper, not the wallet itself. the seed phrase is the actual "wallet"

How do I export one hardware wallet to another from different manufacturer?

I think you are missing the point of hardware wallets. Those are only the "key keepers" not the apps.
Use them with Electrum, Sparrow and you will have full coin control.
Anyways, for me ALL hardware wallets are a waste of time and money. Just a heavy marketing campaign to sell you a piece of crap. Keeping safe your wallet keys is not really necessary to use a HW.
