Mikrotik Chateau 5G - Use LTE as main and Ether1 as fallback

RouterOS Beginner Basics
1

Hello,
i am trying to setup a chateau so that i can use LTE as my primary internet provider, and WAN1 port (ether1) as a fallback ISP. on my current setup my LTE connection is way faster than my ISP, but occationaly (once every 15-20days) LTE goes down for a few hours. i want to be able to fallback to landline ISP for that time.
when i connect ISP on a LAN port, and chateau detects internet on it, it automatically adds a route and makes LTE route distance 2 while WAN port route distance as 1, giving priority to WAN port. how can i swap that, so that i can setup WAN port as a fallback?
my current config is this (default mostly):

In dhcp client settings for ether port, set distance to 5 or more.
On lte side, similar but lower then 5.
If you set one of the ip addresses manually, you normally also set the route manually. Set it then how you need them to be. Lower distance for lte, higher distance for ethernet.

And that should be it.

Don’t use detect internet. Strange things happen sometimes.

that seemed to be pretty easy. Thank you.
i just had to firstly set interface/detect-internet/detect-interface-list=none
so that i can manually add the dhcp client for the lan port.
