TFTP

dnf in tftp-server
firewall-cmd --add-service=tftp
systemctl start tftp.socket

if you want to make it permanent instead:

firewall-cmd --permanent --zone=home --add-service=tftp
firewall-cmd --reload
systemctl enable tftp.socket
systemctl daemon-reload

if you only want to bind to a specific IP/port:

/etc/systemd/system/tftp.service
