How to uninstall/delete OCLP fully from main drive?

Hello,
I got Mac mini with dual drive(classic SSD + NVMe).
I installed Ventura on classic SSD via OCLP but to make it possible I had to run it first on main drive(NMVe with Monterey).
How to make sure it's now fully unistalled/cleared on main drive and it's only on second drive?
