"To connect Trezor with MetaMask on Android."

Currently, it’s not possible to connect Trezor with the MetaMask app for Android, nor is it possible to download a Google Chrome extension on mobile devices. However, there’s a mobile browser called Kiwi that allows the installation of Google Chrome extensions on mobile devices.

Does anyone have knowledge of how secure it would be to use this option?

Hi have you seen this latest feature maybe you try ledger: MetaMask Mobile now integrated with Ledger Nano X | MetaMask News

Of course, I am aware that it is possible with Ledger. The question is related to Trezor.
