Hi, I'm still quite new to RouterOS's scripting, can anyone perhaps help to say how I would disable an DHCP server in a script?

What ? Simply do not configure a DHCP Server...

To disable
To enable
If you have multiple DHCP servers, use /ip dhcp-server print to find the number corresponding to your server.

Do not follow that advise! You should never use numerical index in scripts.
Try something like:
Change the find to your needs.

You should never use numerical index in scripts.

Any particular reason?

But for most entries with a identifier, you can use the name instead:

/ip dhcp-server disable default
/ip dhcp-server enable default

But for most entries with a identifier, you can use the name instead:

/ip dhcp-server disable default
/ip dhcp-server enable default

Thank you. Good info.
