In TypeScript 4.8, the introduction of converting string literals to numbers will make it possible for you to achieve this.
type IWantGet = `${code}` extends infer U
? U extends `${infer S extends number}`
? S
: U
: never
// type IWantGet = "abc" | 10 | 20
Currently, you can only create a union of string literal types.
type IWantGet = `${code}`
// type IWantGet = "10" | "20" | "abc"
