Canon 450D : How to make shot w/o autofocus

Hi guys,

pls suggest me how to do the stuff properly on Canon 450D.

On Nikon D5100-5300 I can use *set-config autofocusdrive 1***

to trigger autofocus procedure and *set-config focusmode2 0*

to turn  autofocus off after that.

After the capturing photos w/o autofocus I can switch back by

*set-config focusmode2 4
*

So, I need the same for my 450D as well.

Surprisingly *set-config autofocusdrive 1* does nothing on this model

and *focusmode2* setting is absent.

I played with *focusmode* then which initially containes 3 possible 
values only:

*>get-config focusmode*
Label: Focus Mode
Type: RADIO
Current: One Shot
Choice: 0 One Shot
Choice: 1 AI Focus
Choice: 2 AI Servo

But when I set "Manual" there it appears as 4th and does what I need, 
turns autofocus off:

*>set-config focusmode Manual*

 > *get-config focusmode*
Label: Focus Mode
Type: RADIO
Current: Manual
Choice: 0 One Shot
Choice: 1 AI Focus
Choice: 2 AI Servo
Choice: 3 Manual

But after that I can switch back to autofocus by manual reset HW swith 
"AF/MF" on lens only.

So this trick doesn't work for me as i need turn on and off autofocus 
several times during a session.

Could you pls suggest me how to operate properly to achieve remote 
control on my 450D in viewfinder=0 mode?

Thank you,
