In short - got a brand new bike the other day with the DT Swiss XM1700 wheelset. All good, removed the inner tubes to make the tyres tubeless. Rear wheel holds air perfect. Front wheel - air leaking through one of the spokes. Done the water test and clearly saw the bubbles. Not from the valve nor anywhere else. Inspected the rim and tape (rim had DT SWiss tubeless tape installed) - all looks good, no holes, no nothing. Checked the valve a million times - it is super tight in the whole and still it leaks air. Tried with a different valve - same story. I must say that for two hours the tyre didn't loose too much air. From almost rock hard it went to not so rock hard, so it's not loosing much air.
What might be the problem? The only thing that comes to mind is to install a new tape and hope for the best.

The rim and spokes all look and feel great, absolutely no damage or anything like that.

You've not put sealant in yet then?

I had this exact problem myself recently and it was the taping, redid it and it fixed the leak.

I cried removing that hellishly expensive rim tape, that's just unfair Cry Rolleyes

Nope, no sealant. I always first check if the tire will hold air and then put the sealent.
Yeah, I also don't want to ruin a brand new factory made rim. Some say to put sealant and it will fix the issue. I really don't know what to do. I guess even if I need a new tape, I can easily take out the sealant and use it again.

Yeah, I have a syringe and can take the sealant back if needed. it will be more messy though if I need to replace the tape anyway.

The sealant did the job, yay! No more bubbles anywhere. Checked the wheel in water and it was perfect.
