how do I setup VULKAN_SDK environment variables in Debian/Raspberry Pi Os

First things first; I am new to Linux and I don't understand a lot of things. I'm working on a Raspberry Pi OS which is Debian based. There is a file with environment variables: "setup-env.sh". Execute the code in the terminal: source ~/vulkan/1.x.yy.z/setup-env.sh And we are in business.
Except after I reboot, obviously. So how can I set up these environment variables automatically at boot? I am finding a lot of answers saying : sudo ~/.bashrc. But that gives me a "command not found" error. In the Vulkan docs they advise to implement it in *.profile*. But again sudo ~/.profile is command not found on my Raspberry Pi OS. And I found out the hard way that adding a PATH to /etc/environment definitely doesn't brighten your day. It seems so simpel, but most people/tutorials skip over it with the mention "*you are on Linux to you probably know how to.*" These are the Vulkan docs if you wish to have a look: https://vulkan.lunarg.com/doc/sdk/latest/linux/getting_started.html So what is the proper way to setup the VULKAN_SDK environment variables from the setup-env.sh file at boot? Thank you sincerely!
