Supposing you don't need ipv6 and you are on console not having problems of
loosing connectivity I would do
nmcli con mod eth0 ipv4.method manual ipv6.method ignore autoconnect yes
ipv4.addresses 192.168.1.15/22 gw4 192.168.1.1 ipv4.dns 192.168.1.14
nmcli dev dis eth0
nmcli con up eth0
just tried on a CentOS 8.1 with Network Manager and configured with dhcp.
