I can’t speak for all, but I think I would be correct in saying that the vast majority do not.
They are not adherents to the Christian faith, and while some might be inspired by Scripture just as some Christians might draw inspiration from other faiths or other holy books, I haven’t ever encountered one who follows the teachings of the Bible. However, some teachings are universal between most faiths (like how thievery is wrong) and therefore they might follow some teachings that they happen to share with the Bible coincidentally.
The reason I’m being so hypothetical is because what one would call “Paganism” or “Heathenism” isn’t an established body of believers with universal precepts. Many modern adherents are fairly individualistic in their beliefs, and therefore no one can say for sure if all have certain beliefs/follow certain teachings. However, typically most would not follow scriptural teachings out of religious conviction.
