Having a revved up immune system is exactly the opposite of what people with autoimmune problems want.
Not sure what specific autoimmune disorders you are talking about, but Vitamin D is well known as having a beneficial preventative effect on cytokine storms.
Here is just one of many.

Vitamin D deficiency has been linked, not necessarily the cause. Sounds like it might help though.

Conclusion:
It appears that vitamin D deficiency is highly prevalent in patients with RA, and that vitamin D deficiency may be linked to disease severity in RA. As vitamin D deficiency has been linked to diffuse musculoskeletal pain, these results have therapeutic implications. Vitamin D supplementation may be needed both for the prevention of osteoporosis as well as for pain relief in patients with RA.

“Vitamin D deficiency is associated with the clinical activity of the disease,” the authors wrote. “The quantification of serum 25 (OH) D levels and, consequently, vitamin D supplementation, should be considered in the management of patients with RA.”
While this is the first study to look into how a person’s vitamin D levels could impact the course of a person’s RA treatment, the link between vitamin D and the condition is well known, said Dr. Daniel Small, a rheumatologist at Mayo Clinic.
Small said that anyone who has an autoimmune disease, like RA, osteopenia, or osteoporosis and neurological disorders should make sure to get their vitamin D levels checked.
And this one which also associates Vitamin D with RA, but says once RA has set in, another approach other than simple D supplementation may be needed due to a sort of Vitamin D desensitivity.

Although the study was limited to investigating cells in the laboratory, the findings would appear to support the idea that maintaining vitamin D levels might help to prevent rheumatoid arthritis and other inflammatory diseases.
However, they would also suggest that simply taking vitamin D supplements is unlikely to help people with rheumatoid arthritis because their immune cells are already desensitized.
“Instead,” notes study co-author Dr. Louisa Jeffery, also from the University of Birmingham, “much higher doses of vitamin D may be needed, or possibly a new treatment that bypasses or corrects the vitamin D insensitivity of immune cells within the joint.”
The researchers now want to take the research further and find out why rheumatoid arthritis causes immune cells to become insensitive to vitamin D, and how this might be prevented. They also want to find out if there are similar effects in other inflammatory conditions.
It could also be that it might just take time to sensitivity to come back once the deficiency is erased....kind of like how folks can reverse adult onset diabetes if they have the willpower to shed their bad food choices.
In any event, it sounds like extra Vitamin D would not hurt any, and might help. And if you are getting the D by being out in the sun exercising, might help even more, with a bit of synergism.
