Can a woman perform Pilgrimage to ziarat in Iraq and Iran without husband’s permission. Husband is simply not interested in religious services at all.

She needs his permission. If he is being reasonable in his denial of permission (like safety issues, or need for personal intimacy) then she cannot go. But if he doesn’t give permission just to hurt her or because he doesn’t believe in Ziyarah (and he would allow her to visit other places like vacation places) then she doesn’t need his permission.
