Edit: to answer your actual question, you can't do it from anywhere except Recovery Mode, so anything you do must be done from there.
Tested on a similar 4,1 upgraded to 5,1 [but I have a flashed graphics card so I could see what I was doing]
Reboot & at the chimes hold Cmd ⌘ R for about 10s.
Wait until you get to Recovery Mode, which for me took approx 45s from the chimes [I'm on SSD but I think it may have chosen a Recovery on another HD to actually boot from] Give it a minute or so just to be safe.
Fn Ctrl ⌃ F2 will switch focus to the menu bar, specifically the Apple logo, top left.
It appears that whatever you have set in System Prefs > Keyboard for "Use all F1, F2 keys as standard function keys" that this option is disabled in Recovery, so even though just Ctrl ⌃ F2 works for me in a running OS, in Recovery I needed the added Fn key.
From there, you can navigate using the arrow keys

From that you can see that Terminal is 4 to the right, then 4 down.
It's 4 not 3 because the first down arrow opens the menu.
Hit Enter & Terminal will launch.
Type csrutil disable & hit Enter
Type reboot & hit Enter.
If it reboots, you got it right - otherwise you'll have to have another guess.
BTW, golden rule, as you have discovered, is keep your crappy old stock Apple card somewhere safe, for occasions such as this ;-)
Additional note: Fn Ctrl ⌃ F2 is a toggle. First will select the menu bar, second will deselect, so make sure to only do it once.
Answer from Tetsujin on Stack ExchangeSo ive downloaded a program that requires me to diasble sip. How risky might this be and is there a way to screen a program for malware before running it with SIP diasbled?

This blind method worked for me:
In order to disable or enable SIP (System Integrity Protection) without being able to see recovery mode and launch the terminal, you can use single-user recovery mode which takes you right into a command prompt.
Reboot Mac holding down CmdRS
Wait 30-60 seconds depending on how fast your boot disk is.
Then hit ENTER a few times to get to the command prompt
To DISABLE SIP: type
csrutil disable; rebootand press EnterTo ENABLE SIP: type
csrutil enable; rebootand press EnterOnce back in macOS you can check the status of SIP with the following command:
csrutil status
Note: This will only work if the recovery OS is =>10.11 (El Cap). If you upgraded (chances are as we are talking a 2011 Mac, the recovery partition will be @ Lion or some such and will not have csrutil in it. Work around is to "recover"from a boot USB with =>10.11 on it.
