|-sda1 { installation pendrive }
nvme0n1 // not showing my partion (this is my nvme internal ssd )

By the sound of it you are running into the issue with installing Linux on machines with RST (Rapid Storage Technology) enabled.
In summary (most) Linux systems have no support for Intel’s RST RAID mode.
See here for some more info:
The Linux-side solution for this is to change the storage controller mode from RAID to AHCI.
It seems however that this won’t work for you, since you are using an Optane cache. In Windows this feature only works by using Intel RST drivers, and requires RAID mode in the EFI.
Unfortunately I think you are stuck with this choice, unless a more experienced user can offer a complete solution.
I downloaded Intel RST setup application from intel Using that I disable the intel RST, it was also automatically disabled in BIOS. But there was no option for AHCI.
it was showing
storage: NON RAID
controller type: NVMe
controller interface: TM
