52k student loan, what’s the best course of action?

Acquired 49k of student loan obtaining my Masters, thankful for the VA because this probably would have been more. That said, i’m still somewhat dumbfounded, I don’t have a grace period since it’s all unsubsidized. I have acquired about over 5k now in interest on the course of 1 and a half years or so. I have a repayment plan of 10 years with a total monthly payment of 661.98. So that said I would have paid about 80,099.58 once my payment plan is completed in 10 years. So about 31,100 in interest paid. Now i am roughly making 135k on my first year after finishing my masters. Just for context my interest rate for 16,800 is 6.8% and 7.83% on 36,167. I do have a subsidized loan of 2,598 with interest of 4.2%. Would I be able to consolidate and refinance for a lower interest rate through another lender or would this be the best course of action? Thank you for all the inputs and tips!
