ISC DHCP HA on RHEL 7.5 without shared storage

First of all, a very good day to all.

Newbies here are asking for a question, can I create a High Availability DHCP server without using shared storage? Both server is identical and connected via Metro-E infra (of course in Data Center). And, if RHEL HA are unsuitable for DHCP HA, kindly explain why.

Kindly ask if my information was short or not enough

Thank you for your help,
