Not entirely. Valorant's anti-cheat tries hard to detect DMA cards, which eventually led to one of their largest banwaves. See:

Of course the cheat developers don't sit idle, so this is far from over.

I read this article, unless I missed it Brazilian pixel bots comprised the bulk of the ban wave, with DMA cheaters getting a mention but of unspecified quantities, and could have been swept up in manual and rage hacking bans?
