Can I specify "--key-type ecdsa"?

[droplinxuser]

With the new vhost command:
./vhsetup.sh -d example.com -le xxx@gmail.com -f

How can I specify to use (--key-type ecdsa) Certificate?

It's not supported. If you only have a few domains, can manually apply the cert with the certbot command with the parameters you need.
e.g.

./vhsetup.sh -d example.com
certbot certonly --non-interactive --agree-tos --key-type ecdsa -m example@example.com --webroot -w /var/www/xxx -d example.com

or download the script and custom the certbot command.

Okay you mean this:
https://github.com/litespeedtech/ls-cloud-image/blob/master/Setup/vhsetup.sh#L642-L644

What is the feature difference of the 2 domain/vhost script?

https://github.com/litespeedtech/ls-cloud-image/blob/master/Setup/vhsetup.sh

1. Correct
2. The domainsetup.sh script is mainly for the cloud image user's first-time setup only. Then they will need to use vhsetup.sh for the rest virtual host setup.
