If this is what I suspect it is, the only way would be ‘guix shell 
--no-grafts’.  This will disable any security fixes that haven't 
yet made it to master.

I don't recommend it, beyond testing it to see if grafts are 
indeed to blame, and perhaps narrowing down how.

If it is due to grafting, it's a long-time known annoyance, yes. 
I searched (twice) to find a specific open bug report to give you, 
but found nothing.

(Almost certainly a failure on my part; don't open a new one ;-)

I say annoyance because it's nothing more for most people, but if 
bandwidth is a serious issue for you the best way to see it fixed 
is to dig in.

All generalisations are false, as they say:

~ λ guix shell qtbase
…
19.4 MB will be downloaded
 qtbase-6.3.1  18.5MiB …
𝕘 qtbase ~ λ exit

~ λ guix shell qtbase:debug
…
321.6 MB will be downloaded
 qtbase-6.3.1-debug  288.2MiB …
𝕘 qtbase:debug ~ λ exit

Kind regards,
