NCP security-check error concerning config.php

I get an security-check error concerning “trusted-proxies” in config.php. This was discussed here https://help.nextcloud.com/t/who-writes-into-my-config-php-nextcloudpi-17-03/71447 however there still is no solution. nc-init is writing my “external.ip.adress” into the “trusted-proxies” section of config.php.
How can I eliminate this behaviour? . From where reads nc-init the ext.ip?
Im running NCP 1.46.7, NC 22.2.3 on a Raspi 4B
