Thyroid Eye Disease outside of Graves is very rare.
We do see reports of professionals incorrectly dismissing the possibility of it occurring on the basis that someone isn’t hyper alone.
This is a collection of sources highlighting evidence that it does.

Thyroid eye disease or Graves’ orbitopathy: What name to use, and why it matters
frontiersin.org/articles/10...
“While most cases occur in the setting of the autoimmune hyperthyroidism caused by Graves’ disease, about 10% of patients will not be hyperthyroid at the time of the ophthalmic diagnosis”

“In most cases TED is related to Graves' hyperthyroidism, although some patients will have no measurable abnormality of thyroid gland function.”

“In most patients, the same autoimmune condition that causes TED also affects the thyroid gland, resulting in Graves’ disease. Graves’ disease most commonly causes thyroid overactivity (hyperthyroidism) but can also rarely cause thyroid underactivity (hypothyroidism). TED can occur in people when their thyroid is overactive, underactive or functioning normally”

The Pathophysiology of Thyroid Eye Disease (TED): Implications for Immunotherapy
“TED is most commonly associated with hyperthyroidism, however patients may be hypothyroid or euthyroid.”
It is also interesting that autoantibodies formation is not always present.
So this would explain how TED can occur without TRab, but the severity can be closely correlated.
“The proximate cause for hyperthyroidism in GD (Graves’ disease) is secondary to activating autoantibodies to TSHR. However, TED can present independent of GD, endocrinologic manifestations or autoantibody formation. Generation of activating antibodies against the TSHR correlates with TED severity, but there is currently no evidence to indicate that autoantibody production is the cause of ophthalmopathy.”

“Thyroid eye disease is most commonly associated with Graves’ disease. It can also occur with normal thyroid hormone levels or low levels of thyroid hormones
(hypothyroidism).”

“TED is also known as Graves' ophthalmopathy or Graves eye Disease because 9 in 10 people have Graves”
“Less commonly, TED can happen to people who have hyperthyroidism without Graves or have hypothyroidism a condition where the thyroid doesn't produce enough thyroid hormone”

“TED often occurs in conjunction with autoimmune thyroid diseases such as Graves’ disease (90%) or Hashimoto thyroiditis (3%)”

“More recently, TED has also been noted in Hashimoto's thyroiditis as well as in the absence of a thyroid dysfunction.”

British Thyroid Foundation
“Q13 Will a thyroid antibody test indicate whether I have active TED?
A. Unfortunately at present there are no specific thyroid antibody tests that will indicate TED activity. In people with Graves’ disease it is essential to confirm the diagnosis of Graves’ by measuring antibodies to the thyrotropin receptor (TRAB). Those with the highest TRAB levels are more likely to have active TED and TRAB levels may also correlate with TED severity. However, TRAB levels can persist even when the disease is completely quiet and some patients with TED never have abnormal thyroid antibodies.”
