Prevent requests to 127.0.0.1 from being forwarded to http_proxy

I have this on my machine:

$ cat /etc/profile.d/proxy.sh 
export http_proxy=http://192.168.1.30:3128 
export https_proxy=https://192.168.1.30:3128 

That works great, until I need to use an HTTP interface with an application on the localhost.

$ wget localhost
--2023-03-02 06:54:52--  http://localhost/
Connecting to 192.168.1.30:3128... connected.
Proxy request sent, awaiting response... 503 Service Unavailable
2023-03-02 06:54:52 ERROR 503: Service Unavailable.

$ wget 127.0.0.1
--2023-03-02 06:55:20--  http://127.0.0.1/ 
Connecting to 192.168.1.30:3128... connected.
Proxy request sent, awaiting response... 403 Forbidden
2023-03-02 06:55:20 ERROR 403: Forbidden.

Is there a way to prevent localhost and 127.0.0.1 requests from being forwarded to the proxy? --- Details: This machine isn't connected directly to the internet. It has no gateway or default route. But it is on a LAN with a proxy machine (192.168.1.30) that has a proxy server installed (port 3128) and has an internet connection.
