Regardless of the code or standard, you are limited by the material listed by the WPS. If the WPS only lists API 5L Gr X65, that is all you can weld in production.

You may be able to revise the WPS to include additional base metal specifications to the extent permitted by the specific welding standard. Each welding standard or code groups the base metals differently. As such, you must refer to the applicable standard to see what materials can be included in the WPS.

Per ASME the base metals are grouped by the P number. Per API the grouping is based on strength and limited to carbon and low alloy steels if I recollect. AWS B2.1 uses M numbers that are similar to ASME's P numbers, but is more inclusive.

So, it all goes back to what is included by your WPS.
