howto remove /endpoint/ part of the url for http node

[myB0B]

i have a currently a docker node-red & domoticz installation working for years
i decide to migrate to home assistant (supervised) on a RPI5 with node-red install as module

the problem is than a have tons of IOT objects who use http node like http://mynodered:1880/something
and in Node-Red integration on HA url change to http://mynodered:1880/endpoint/something

the problem is i can't change all my IOT objects to reflect the new url

how to remove the /endpoint/ part of the url ?
