>It it possible to reset your Trezor and cancel it if the seed phrase is wrong?
No. A reset (wipe) will erase your seed phrase and cannot be recovered unless you know it.
What you actually want is a Dry Run Recovery (Check Backup). It allows you to put in your seed without wiping, and without actually making any changes. It simply tells you if you are right or wrong after you put in the seed phrase.
To do this, open Suite -> Settings -> Device -> Click on „Check Backup“ and follow the prompts. There is no risk in this, as no changes will actually be made and you will then be assured that you know the seed phrase (or that you don’t know it, if that is the case)
