He might use some special jutsu or seals. For example, he could use a sealing technique to suppress the signs of his bloodline. This way, others wouldn't be able to detect it through normal means like sensing chakra.
Perhaps he just acts in a way that doesn't draw attention to his bloodline powers. He doesn't show off any abilities that are obviously related to his bloodline and instead focuses on more common ninja skills in public.
Another possibility is that he uses some sort of disguise or misdirection. He could create false chakra signatures or pretend to be a normal ninja without any special bloodline. This would involve a lot of skill in controlling his own chakra and fooling those around him.
It could also be part of a strategic move. By hiding his bloodline, he can surprise his opponents in battle. They would underestimate him based on not knowing about his true powers, and then he could turn the tables on them when the time is right. This gives him an edge in combat situations.
There are also fanfictions where a bloodline is created through some sort of experimental jutsu. For example, a bloodline that allows the user to transform into different elements at will. This would give the character an edge in combat as they could adapt to any situation by changing their form.
The knight bloodline could be integrated as a foreign power that was brought to the Naruto world long ago. Maybe a group of warriors from another dimension with the knight bloodline came and settled, and over time their bloodline got diluted but still resurfaces in certain individuals.
In some fanfics, Naruto absorbs the bloodline through a special jutsu. For example, he might find an ancient scroll that contains a jutsu allowing him to transfer and absorb the genetic traits related to a bloodline.
It could completely change the dynamics of his powers and his journey. Maybe he'd have an easier time mastering jutsu or face new challenges related to his unique bloodline.
The Ranton bloodline in Naruto fanfiction can bring really cool and unique abilities. It might include things like controlling water-based attacks in a special way.

In fanfiction, a fem Naruto with a unique bloodline can open up many interesting storylines. For example, her bloodline could give her enhanced sensory abilities, allowing her to detect enemies from afar more easily. It might also be related to some special jutsu that only she can perform, like a new type of elemental manipulation.
I'd recommend 'Bloodline's Ascent'. This fanfiction delves deep into the concept of rare bloodlines in the Naruto universe. It has some really cool battles and the way it weaves the original Naruto lore with new bloodline ideas is fascinating. For example, the main character discovers a long - lost bloodline that gives them extraordinary powers.
In Naruto fanfiction, the concept of a bacteria bloodline can be really interesting. It could potentially give the character unique abilities. For example, they might be able to control bacteria for various purposes like healing or creating poisons.
