I am performing a small study. This model has passed construct reliability, convergent validity, and construct validity. However, discriminant validity is not achieved. Is "Discriminant Validity" possible for two latent variable model. Any guideline from literature. Any advice ?

@Hannan Yes it can be established with only two latent variables also. Refer to page 12 of the attached manuscript below.
https://journals.sagepub.com/doi/full/10.1177/1094428120968614
When two latent variables are more highly correlated than expected based on your theory, they may lack discriminant validity. So evidence for discriminant validity would come from correlations that are "not too strong", whatever that means in your case/theory.
The same guidelines as for observed variables apply (see, e.g., Campbell and Fiske's 1959 guidelines based on their multitrait- multimethod matrix approach), except that latent variables tend to be more highly correlated than observed variables, due to the removal of random measurement error in latent variables. So in that sense, latent variable analysis offers a stronger test of discriminant validity.
Respected Dr Bilal Mustafa Khan it would be very helpful, if you can share that excel sheet.
