I have searched this weekend for FTA channels that have no EPG and could be interesting for the Western European viewers (either they transmit for W-E or have interesting content). Possibly for some of them there are no sources, but maybe you can have a look at the list to see if some can be added (there are also a few channels that had EPG but changed serviceref because of a move)
Quest +1 1:0:1:1847:7F3:2:11A0000:0:0:0 (Quest does have EPG)
CGTN documentary 1:0:1:369:3C28:13E:820000:0:0:0 (guide on site https://www.cgtn.com/channel/do.do but as far as I can see only for the current day but maybe you have a source)
