How to disable/change default distance/route of Huawei E3372 4G USB modem

Hi!
I’ve a Mikrotik RB760iGS with 2 connections with distance 10 (main connections) and 20 (alternative connection), when first connection, distance 10, goes down all my computers goes out using the backup line with distance 20, now I want to add an USB LTE Modem Huawei E3372 but when I connect that USB Modem it adds a default route with distance 2, how can I change that default route by default to 30 or disable it? I mean if the mikrotik reboot for any reason it adds that default routes making all computers to go out by the LTE Modem and never by the main connection with distance 10.

Please don’t say “Just assign 1 to main connection” because I’ve 2 connections than the LTE one

Thank you

Ok I found a way to do it, just I add a dchp client for the LTE modem with my settings:

/ip dhcp-client
add add-default-route=no dhcp-options=hostname,clientid disabled=no interface=lte1
