From the comments it sounds like you are trying to override what the sysadmins have setup for you. This could likely generate some decent backlash against you as the policies are likely there for a reason.
I would recommend:
Talk to the sys admins of your setup. Don't call them and tell them you need it removed, tell them what is wrong and ask them if there is anything they can do to change this. Remember in some instances it may not be in their power to change this, but it won't hurt to ask for help.
Be knowledgeable about your setup. While you indicate the connection to the corporate network is slow, is it your home network or the corporate network. In a lot of instances that I see the home network is fine but there is a misconfiguration related to the vpn connectivity that causes the connections to be slower than expected. Overall maybe it is just an issue with the laptop they provided you and not with the network at all. Try and explain as calmly as you can about what it you need to do exactly. Remember the policies are there for a reason.
Be open to pushback on policies. A lot of sysadmins default responses will be no, be open to this and keep try and be polite about the issues you have, it will get you a lot farther than being forceful. Try and understand why the policies are in place, even if they aren't the best for your setup.
Ask if you can use your own equipment. Maybe you do not have a home laptop, or maybe they require you to use a company pc to connect. Ask IT if they can check your home computer and allow you to use it to connect remotely.
The settings you have in place are likely controlled centrally and cannot be easily overridden. Even if you were to change the settings it is likely they would be overridden next time you logged in.
After all that here is how to override it. This is not recommended as unless you have a really BOFH IT department if you are calm and try and work with them on your issues they will help you if they can. Keep in mind sometimes people's hands are tied with red tape.
Create a new local account and login with it. Make it a local administrator on the machine and login as that account, authenticate where needed with your work credentials. If that doesn't work unjoin the computer from the domain. This could cause IT a lot of headache and possibly make your laptop unusable, but may get you what you are after.
