Seems not to.

If you really need to do this (which I think is a bad idea, but
that's not of interest here), it's a matter of a few seconds to
write a setuid C wrapper program like this:
#include <stdlib.h>
#include <unistd.h>
int main(void)
{
setuid(geteuid()); /* optional */
system("my_shell_script");
return 0;
}
