How to disable Basic Auth for Owncloud location?

Hi all,

I have several locations in my Nginx config file. I have Basic Auth enable for these locations.
I want to disable Basic Auth only for Owncloud location in my config because I don't want autologin every time I open Owncloud homepage (It is happen when Basic Auth password is the same as Owncloud user password).

So again, how to disable Basic auth only for Owncloud location in my nginx site config?

I attach my config.

Thanks for help
