Is it possible to make peace with the Dawnguard after joining the Vampire Clan?

[Akfiz]

SPOILERS ALERT!

I played the Dawnguard storyline the way you would expect, went to the Dawnguard castle, set that vampire girl free, she took me to her dad who made me a vampire, I had the option to refuse but I thought he would just turn hostile if I do so. I finished the whole campaign and now the Dawnguard hates me.

Turns out, if you refuse his offer you side with the Dawnguard, if you accept his offer (which I did) you side with the Vampire Clan. I thought the story was linear and you'll eventually rejoin the Dawnguard or something, but it's not. The moment of choice is long gone and the story is completed. And now when I go to Ford Dawnguard the Dawnguards just attack me.

It is possible to make peace with the Dawnguard and improve my relations with them?
I'm not a vampire anymore but they still attack me on sight when I come to Fort Dawnguard.

Other than reload an old save from before I made the choice to accept or reject Lord Harkon's offer.

Do the word irreconcilable differences mean anything to you.

Dawnguard are a group of Vampire Hunters, who want to kill every vampire in existence.
Volkihar Vampires are a group of pureblood Vampires, who want to take over the world.

There simply isn't a compromise that will work between them.

The vampire lord is dead, the sun isn't dead and I'm no longer a vampire.

The game isn't very good at realising that.

As far as the Dawnguard know, you're still a Vampire Lord, and still plotting to turn humans into cattle for the various Vampire factions in the world.
And they don't stop long enough for you to convince them, they try to kill you on sight.

They are going to stay enemies I'm afraid.

ABANDONED REASON for once you turned vampire they will attack on sight and not make peace

Have you tried to roleplay it?
Raise your speech skills to become the smooth sweet talker to make friends of anyone.
Or use the seduce spell to turn Isran or the dawnguard into compliant friends.
Or using the better pacify spells to be able to move amongst them.

Dawnguard doesn't want you to be able to do any of this really.

In my vampire side play through I kept still wanting to get the spells that the dawnguard members sell Vampire's bane and Sunfire. So after each main vampire mission I would fast travel to Riften then check out the Dawnguard progress and was amazed that Sorine and Florientius didn't appear in my game until I had been to forgotten valley and had Auriels bow.

For members dedicated to fight Vampires the Dawnguard all sleep through each night. On each visit I could have silently feed on each sleeping member.
