Can the Samsung Galaxy Note 4 - 5.1.1 from Verizon be rooted?

[MSB14]

I accidentally factory reset my note 4 and I was trying to recover my text messages and I keep seeing that my phone was not rooted. So I've been searching all day to figure out how and came upon a few youtubers that say they can .... and when I look further I always see an asterisk that states Note 4 with 5.1.1 from Verizon can not be rooted. What is the truth? Am I out of luck? Will I ever be able to recover my messages?
