Yes you can tamper the executables if it's you on your pc compiling the code and upload it to the release page...
BUT if you use ci/cd pipelines, you can almost be sure it's not a human who is in charge of compiling. It's a robot who automatically clones the repo, launch the build and upload the artifact to release. It's much more transparent this way
Want to go really cheap and tighten a broad range of newton meters? Use a wrench, a luggage scale, a calculator and science lol

People use this trick to calibrate torque wrenches... I use it to tighten my motorcycle brake caliper bolts
