@sneha.sadaphal - Hi. As it is today, it looks like there is no access for tweaking components in a presentation document.
I found that you may be able to access existing tweaks from the browsernode and access some properties though:

I took a little dive in a presentation document and my guess for the closest property that I can see is the PresentationComponent.Transformation which is a matrix (I'm thinking it could be a similar vein to AssemblyDocument > ComponentDefinition > ComponentOccurrence.Transformation), but it's only available to get, not set (like many of the other PresentationComponent object properties are).
