Patching OTP FW

Is it possible to patch a FW in written to OTP? I read some app notes that indicated that it might be possible by using SPOTA. According to UM-B-011 there is a part of the retention ram 0x81A1F to 0x81FFF which holds SPOTAR patches. The original FW does not implement SPOTA however. I suspect the bug is caused by SDK 3.0.8.0 and fixed in 3.0.10.0 so the change required may be quite large.
