I have a method that cannot be @nogc only because it concatenates strings for a long exception message, as seen below.

            throw new ASN1ValuePaddingException
            (
                "This exception was thrown because you attempted to decode " ~
                "an INTEGER that was encoded on more than the minimum " ~
                "necessary bytes. " ~
                notWhatYouMeantText ~ forMoreInformationText ~
                debugInformationText ~ reportBugsText
            );

Those variables you see are immutable. Is there a way that I can combine these strings together at compile time, rather than having a really long string that exceeds the 120 hard line-length limit?

All strings are immutable.
But can they be enum?

This will be concatenated at compiletime and there will be no runtime overhead iff those are static immutable or enum.
