Is there any way to determine if a .NET assembly was compiled with the "deterministic" flag?

Question

I am using code from this answer to get the linker timestamp of a .NET assembly.

However, if the assembly was compiled as "deterministic", this value is not an accurate measure of when the assembly was built (reference), and so I want to ignore it.

Is there any information in the PE header (or any other part of the assembly) which indicates that it's been built as "deterministic"?

If there was, I'd expect it to be an attribute contained in the `CompilerServices` namespace, but I can't see any likely suspects there. — Damien_The_Unbeliever, Nov 01 '18 at 14:48

NuGet Package Explorer can be used to find out if an assembly in a nuget package was built using the deterministic flag.

Looking through the source code there seem to be multiple checks before marking an assembly/whole package to be built deterministic. Looks like they implemented everything of this answer in code to find out if an assembly was build deterministic.
