Is it possible to use zod schema as type and constrain it?

I have few Zod schemas. Let's call them Schema1, 2, 3, 4 and 5. I am trying to create a function that should allow only schemas 1 and 2 as its second parameter

function someFunc(parameter1: any, schema: ???) {
  schema.parse(.....)
  // And do something else
}

I know I could type the schema in the function as z.ZodTypeAny, but then that would allow all the schemas to be passed into the function. Is there a way to constrain the schema parameter so that it would only allow certain type of schemas passed into the function?

As suggested in comments, that could be the trick for you.

function someFunc(parameter1: any, schema: typeof schema1 | typeof schema2) {...}

You can also (I suppose) create a dedicated type :

type typeForSomeFunc = typeof schema1 | typeof schema2;
function someFunc(parameter1: any, schema: typeForSomeFunc) {...}
