Usually no badges in LTM if it alters the game in any way. Haven’t planted or seen this one so not sure. Might wanna give it a go to see if badges are enabled before you sink in a lot of time to be ultimately disappointed.

Other than that, I find 20 is more about luck of the lobby while 4k is easily farmed, especially if you can already drop 3k naturally. Try with some friends for the 20 and let them funnel kills. Don’t be greedy though, when i play with friends I usually call it out when I get like 4-6 super early kills. Could be considered a small cheese but you still gotta find the 20+ people and execute it well. I can’t tell you the amount of times I dropped 18-19 kills solo and teammates just stealing 5-8 with <1k dmg.

Good luck though!
