Allergic to acrylic mold (ITE)

I posted about having really itchy ears before. After many many months of trying different over-the-counter and prescription things, long story short, as suspected, I’ve been told I’m likely allergic to the acrylic molds. In the end, had to be prescribed some cream that actually lowers immune system; it cleared up within a couple days but due to the nature of the cream, it’s not for long term usage so don’t think it’s wise to wear and use cream.

Is there anything that can be done short of having a different material? Like can you coat it with something? I don’t think the hearing aid place at my hospital does different materials as I asked about silicone before.

My ears doesn’t just get super duper itchy, but end up shedding the entire skin in my ear canal within a month or so if I consistently wear it (wake to sleep everyday). I can wear it sporadically everyday without issue (e.g. only when I play music or have a meeting), or wear it alternate days with minor itching, but then I just forget about wearing them since my loss is “mild”. There is a large enough difference for me that I want to wear them but general day-to-day it’s subtle enough to forget too; 100% notice when playing cello.
