I want to try it on a new a new node (fresh installed, and not upgraded from 7.4)
the node dont have kernel 5.15.116-1-pve installed

is it the flow:

proxmox-boot-tool kernel add 5.15.116-1-pve
proxmox-boot-tool pin 5.15.116-1-pve
proxmox-boot-tool refresh

after reboot does the kernet 5.15.116-1-pve will be loaded?

You would need to install it from the PVE 7 repository:
