You can use a custom mapping that has a removeAllNodes and specifies the group to remove.

message.removeAllNodes('OBR[group=!OBR;/OBX-5=*]');

OBR[group=!OBR is used to select the the nodes including OBR OBX NTE until the next OBR.

; can be used once within the brackets [ ] adn is used to add another set of criteria.

/OBX selects any OBX segment after the OBR node.

If you have multipe OBR groups then the OBR, OBX, and NTE will be removed of any OBR with OBX-5 = *
