According to a post from the linux-poweredge mailing list [1], removal of those packages should be sufficient:

yum remove dell_ie_rac python-smbios

However, OMSA may not start afterwards, due to some changes in the NVMe monitoring.
They now use a custom library, which segfaults on unsupported distributions. See [2] for more details.
Of course, Scientific Linux and CentOS are not supported.
