hm, is it possible to hide the code somehow, like obfuscating or something like this?

No.
Since the native instruction set of each gpu model is be different, the driver will compile a binary based on a pseudo assembly language stored in the file. Unlike FPGA bitstreams (that are run encrypted onchip), gpu binary kernels are open. Protecting the exe file doesn't really help, because you can extract the assembly code by snooping the driver. To protect kernels coders can alter the hash abit. They can rename tablenames to make it less readable. But they can't hide how they managed to get the speedup. As you can see from the SIMD-512 t-rex disassembly they use sharedmem instead of slow DDR5 mem to store table data.

Here is the latest GPL licenced code (with 7 opensource coders work in it):
