Full disclosure, currently employed at Branch.
You can certainly create a single link and append query parameters like you have in your example, but you'll need to integrate the Branch SDK & make sure you've set up an account. More info on creating those types of links here.
Branch uses a reserved keyword called "$deeplink_path" that allows you to specify the portion that comes after "frock://". Simply do the following:
https://bnc.lt/a/key_live_xxxx?$deeplink_path=%2Freset-pw%3Ftoken%3Dabc
and Branch will pass through that token key value pair. (again, assuming you've set the SDK up and registered for an account).
