You’ d expect them to be as like other disciplines CX has adopted tubeless (although there are still people using tubs but not many starting down that route anymore). But it doesn’t say so check.
It isn’t what you are asking but I rate vittoria tyres highly (grip, puncture resistance, tubeless setup). I run them on my mtb and will be switching my gravel bike over when I wear out the Gravel Kings that I have on there now.
I saw these which are pretty similar to the Contis. There is a zero version which is even more slick (that I’ve just bought to commute on).

I think they are tubeless from the part number but you might want to double check.
