Yes, but first will test it a little to check that rngd still works. *** Bug 2154804 has been marked as a duplicate of this bug. *** Reproduced with jitterentropy-3.4.1-1.el9.s390x and rng-tools-6.15-2.el9.s390x, verified with rng-tools-6.15-3.el9.s390x.rpm and jitterentropy-3.4.1-2.el9.s390x.rpm :
# uname -r
5.14.0-242.el9.s390x
# cat /etc/redhat-release

# dnf install rng-tools
(...)
Installed:
jitterentropy-3.4.1-1.el9.s390x
