Yes because in the elf file, we have .flash.text section instead of .text You can rename the section names. e.g;

cp build/hello_world.elf build/gprof_hello_world.elf
xtensa-esp32s3-elf-objcopy -I elf32-xtensa-le --rename-section .flash.text=.text build/gprof_hello_world.elf

I wrote a HOWTO that brings all this together as I couldn't find it anywhere else, if someone comes looking for help here:
