Hello zameer,
If you want to change the menu position on the header from left to right, it may cause problem and it need a high level of customization with CSS although can you please check once by adding the below CSS codes on Appearance > Customize > Layout/Design Options > Custom CSS and check whether your need may achieve or not?
.header-wrapper .acmethemes-nav {
float: right !important;
}Let us know about the results.
Warm Regards
