The reason trans tape or kt tape or other sports tape is safer than elastic bandages, is because tape isn't applied all the way around the chest, but just on the sides, with gaps of no tape at the front and the back, so you can breathe. If your nipples against your shirt are the main irritation, you can also only tape your nipples (protect them from the adhesive though), to smooth them down. Bandages are worse than binders because they constrict all the way around, whereas binders are usually constructed of both stretchy and stiff material, that also has a controlled limited hug by the size of the garment - binders won't constrict you tighter than the size of the garment, whereas bandages just wrapped around will squeeze you too tightly and are difficult to control how small it wants to shrink and how safe that size is and you risk breaking a rib or worse. With any garment that binds you with compression (ones that wrap fully around your chest) it is important to take breaks and wear for no longer than 8 hours per day, and find a couple days off per week in which you don't use those methods the whole day. Never sleep in these methods and avoid exercizing while wearing these methods. If you aren't able to get binders because of the association with trans people, do you think you would be able to get men's compression shirts? These are typically what either gym bros wear or cis guys with gyno or extra weight they don't want use to contour the shape of their body under clothes. This video mentions them, to show you what I mean. Edit: If that video isn't available where you are, this and this are the two links to compression shirts that he mentions. If you can't get those specific ones, maybe there are others similar.
