how to build with DEB_BUILD_OPTIONS=noautodbgsym ?

I'd like to try building intel-graphics-compiler with DEB_BUILD_OPTIONS=noautodbgsym as a workaround for issue #247 (closed) (artifacts too large for uploading, skipping the -dbgsym packages should reduce them by 200+ MB), but I didn't see any documentation how to set (or rather extend) DEB_BUILD_OPTIONS (or any other environment variable) for the build targets.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
