Is there any possible branch supporting running linuxptp-related tools without root privilege?

Due to the restriction of the working computer, I have no root privilege. Thus, I've been trying the tools such ptp4l providd by your project and other projects, typically the original maintained by Richard (https://github.com/richardcochran/linuxptp) without root privilege. However, there is always the error like follows:
"""
xxx@weizenbaum:~/xxx/openil_linuxptp_install$ ./sbin/ptp4l -i enp3s0f0 -f configs/automotive-master.cfg --step_threshold=1 -m -S

So is there any chance I can use all the utilities inside linuxptp as a regular user?
