Normally yes, if you're root, you can do all kinds of stuff including
appending 'selinux=0' to the kernel command line. Maybe there are better
SELinux experts on the list, but if you need to partition the power of
root further, maybe MLS SELinux configuration is what you need?

Do they need the full sudo permissions (to become root) ? Can you just
give them permissions to run specific commands (ie /sbin/service etc) ?
