Linux capabilities for non root user

I'm working on converting a root process to run as a non-root user by assigning all available Linux capabilities (38 in total, based on /usr/include/linux/capability.h). Despite this, I'm still encountering some errors.

Are there any operations or system tasks that remain restricted for non-root users even if all relevant Linux capabilities are assigned? Any insights or additional steps I should consider?
Errors I see:

However, the process has all the capabilities:

Thanks!
