Installing NextCloudPi in another directory

I want to say thank you for the NextCloudPi, this is really really easy to build the nextcloud on my Armbian tinkerboard . However, after installing, I found a problem. I want to use my tinkerboard as my web server and also as my cloud server. When I browse https://my_ip, the nextcloudPi install in the root directory and I can’t browse anymore my var/www/html. Is it possible I can browse my NextCloudPi WebUI on my_ip:4443 and go to the NextCloud in https://my_ip/nextcloud ?

Another question, when I was installing, I got this following error:
sed: can't read /etc/php//cli/php.ini: No such file or directory

then it stops the installation. When I was browsing it does not give me any issue though but I am wondering why this is happening? /etc/php/ has folder like 5.6 7.0 7.1 7.2 7.3. I think for some reason it can’t detect.
