No. Surrak's ability isn't "countering" anything. Since Surrak can't be countered, anything that would try to counter it will fail to do so. To be clear, you can still cast Counterflux targeting Surrak. It just won't counter surrak, but will resolve as normal. This is important for things like Remand and Mana Drain as you will still draw a card/get mana if you target Surrak with them.
To add on to that, let's explain what happens here. You cast Surrak, and opp plays Counterflux. Now, Counterflux still resolves, but says "Oh, look at that, he can't be countered" and so it just does nothing. Counterflux resolves, but has no effect.
