I think the use case I reported is a bit different:

$ ip addr
... 
2: enps03   
   inet 10.1.1.30/24 metric 1024 brd 10.1.1.255 scope global dynamic enp0s3

The host has received an IP address from the DHCP server on the 10.1.1.0/24
network.

$ ip route
default via 10.1.1.250 dev enps03 proto dhcp 
10.1.1.250 dev enp0s3 proto dhcp scope link src 10.1.1.30 metric 1024 
10.1.1.0/24 dev enps03 proto kernel scope link src 10.1.1.30 metric 1024 

These settings were retrieved from the dhcp server.

If I add the static route manually after the network has been started and the
host has received the IP configuration from the DHCP server (please note that
the gateway for the static route is on the local network)

$ ip route add 10.2.1.1/32 via 10.1.1.252 dev enps03 

I did not receive an error message, instead the desired route was added.

$ ip route
...
10.2.1.1 via 10.1.1.252 dev enp0s3 

and is reachable

$ ping 10.2.1.1
PING 10.2.1.1 (10.2.1.1) 56(84) bytes of data.
64 bytes of 10.2.1.1: icmp_seq=1 ttl=63 time=1.19 ms

If this works, why doesn't adding this route to
/etc/sysconfig/network/ifroute-enps03 work?
