Fixed!
When I setup my lab, I was having the same issue when deploying VMware vCenter Server Appliance v7.0.1 ova to VMware Workstation Pro 16 when using static ipv4. I can't change the IP from static to DHCP in the Console, Web portal https://vca:5480 or /opt/vmware/share/vami/vami_config_net command via SSH.
Here is the fix. Note, changing DHCP=yes doesn't really use DHCP e.g. you don't need a DHCP server/service for it to work.
1) SSH to the vCenter IP, type shell, edit /etc/systemd/network/10-eth0.network file, change DHCP=no to DHCP=yes, save the file and done! No need to reboot
2) Head over to or refresh https://vca:5480 again to finish the configuration
Sample output below
Command> shell
Shell access is granted to root
root@vca [ ~ ]# cat /etc/systemd/network/10-eth0.network
[Match]
Name=eth0
[Network]
Gateway=192.168.199.2
Address=192.168.199.7/24
LinkLocalAddressing=no
DHCP=yes
Domains=lab.local
[DHCP]
UseDNS=false
[Route]
Gateway=192.168.199.2
Destination=0.0.0.0/0
Once I done that, No more IP information in Step 2 (see attached, No.1) while setting it up via https://vca:5480.
