Question about Bara Imambara's Rule for Men visiting with Women

Hi Everyone, I’m planning to visit Bara Imambara with my girlfriend, and I heard that if a man is with a woman, a tour guide is mandatory. How strict is this rule? Do they actively check at the entrance? If it’s strictly enforced, I’m also considering other places like Janeshwar Mishra Park's new Jurassic World attraction. Any insights would be appreciated. Thanks
