You cannot restore seed phrases on Trezor using Electrum. You can only restore the seed phrase on Trezor via Trezor Suite.
This is not true.
You can restore seed phrase on any wallet that supports BIP39, including Electrum, but it's not recommended to restore seed phrase from cold to hot wallets.
Only problem in this case can be different derivation paths for some wallets that are not standard, or maybe accounts had additional passphrases.
Yes, I know that the Seed phrase generated by Trezor can be used in Electrum (by selecting the BIP39 option when importing it) and vice versa; the BIP39 seed phrase generated from the Electrum wallet can be restored to Trezor T.
The recovery seed is a crucial element for the security of your Trezor hardware wallet. If your device is lost, damaged or stolen, you can use your recovery seed to restore access to your entire wallet, passwords and other data associated with it. The process is simple; you only have to enter the words of your seed into your new Trezor device. (You may also use any other wallets or applications that use the same standard as the Trezor.)
It seems I misunderstood the context of the OP's question.
However, what I mean above is you cannot set up Trezor from scratch using Electrum, but you have to use Trezor Suite to use it with a new seed phrase or restore an existing seed phrase.
