Your rights under the ICA are dead. Since 2002 you were only able
to order it if one end was in a tier 3 wirecenter, and it was
killed in 2021 as an orderable product.
There's an 8 year transition for existing unbundled dark fiber
(February 28, 2029). Dark fiber loops were dead in 2002 under the
TRRO.
Oh, and I forgot to mention that my ICA has it.

Subject: Frontier Dark Fiber
I'm looking for a contact at Frontier that can discuss dark fiber.
My current account exec says they don't offer it, yet prior conversations with him and a previous SE revealed that they very much did (just didn't have availability on the paths I wanted at the time).
Their web site highlights it fairly proudly.
I'm aware that availability varies.
I'm aware that they likely don't want to sell it.
