there's also 3.4GHz band, rarely used, could collide with some radars
433MHz could interfere with some 70cm band radios, depending on how badly are all these baofengs misused
Of course, if you make your own drones from scratch, you can make them work on any part of spectrum, including what is normally advised against. There are tradeoffs to be done, but not all rules of electromagnetic compliance will be adhered to in wartime
I think if their jamming goes up to 3 GHz, the sidebands of the jammer might affect at 3.4 GHz too, but yeah, there is also that one.
The problem with making your own RF systems is that Ukraine would require a steady supply of RF components, which might be hard to secure in war time over off the shelf, which probably have stocked supply lines in most places, through hobbyists stores.
