here is the thing, it makes absolutely no sense to even remotely believe that using the chidori would cause a byakugan user to have tunnel vision.

a normal eye can not see anywhere near 360 degree. its absolutely illogical to believe that the byakugan wouldn't negate the tunnel vision. The visual field of the human eye spans approximately a 170 degrees of arc with around 100 degrees for the peripheral vision.

here is the thing, a person with tunnel vision simply has a loss of peripheral vision, IE someone using the chidori would have roughly a 70 degree range of vision, because of the tunnel vision

so even if the byakugan is effected by the tunnel vision, it wouldn't be that big of a problem because the byakugan user would still have a massive field of vision. 170 goes into 360, 2.11764705882352 times, so a normal human eye's center line vision is 70 degree's the peripheral vision is 100 degree's you take 70 x 2.11764705882352 and you get 148.235294118, meaning the byakugan's center line vision has a 148.235294118 arc, meaning that the byakugan's peripheral vision has a 211.764705882 degree arc. so while a byakugan user might have a loss of 211.764705882 degree's of vision they would still have a higher range of vision than a Sharingan user who simply can mitigate the tunnel vision because of the sharingan's predictive abilities, IE even the sharingan user still has tunnel vision.

and sure roughly 148 degree is less than 170 of an unaffected eye, thats irrelevant there are techniques people with tunnel vision can use to mitigate the vision, one technique is to constantly shift your range of vision from its center, like looking to the right or left for a split second

so in the end, it wouldn't matter, the byakugan user would still be able to use the chidori. and that is if the byakugan works like a normal eye, we don't know what gives the Byakugan the 360 degree vision, it is most likely not anything in the eye itself, because if it was there veins wouldn't protrude from the side of their head, so we don't even know if they would be effected by the tunnel vision
