If this particular variable is essential, it should be included in the model. You may go ahead and build the model including this variable. However, you should check the correlation of this variable with other predictor variables. Drop the variable which is highly correlated with this particular variable. Because highly correlated variables provide the similar information and hence lead to multicollinearity.

Also, after building the model, check if this particular variable is statistically significant or not and take appropriate action in the next version of the model.

Additionally, try Lasso regression. It is an intrinsic method of feature selection and see if this model has included the variable in question.
