Glibc provides ld.so which can:

    --argv0 STRING        set argv[0] to STRING before running

Maybe that could be useful?

I did not know about that possibility! It requires glibc and its dynamic linker though, doesn't seem to be as widely available as the GNU coreutils. I developed lone inside Termux: it does not have ld.so but does have env. There's a GNU binutils ld but it did not recognize the --argv0 option when I tried it.

ld.so is the dynamic linker. It is always used when invoking a dynamically linked program but you can invoke it manually which allows you to specify optionsfor the linker. But the name and path you need to invoke depends on the architecture and possibly distro, e.g. for amd64 these days its

/lib64/ld-linux-x86-64.so.2 --argv0 argv0isalie yourprogramm

ld is the (not dynamic) linker. It doesn't invoke your program at all.
