This is as expected as "P1 Gen 6" is not supported in this package .
Please find link for supported products/wwan modem combination: https://github.com/lenovo/lenovo-wwan-unlock/blob/main/README.md

Sorry to say but Currently , we don't have plan to support P1Gen6 for L860R+ in Linux unless their is business case.
Thank you !
