Hi @Chaitra Dixit ,
I think you have set local site list in Internet Explorer mode pages
list in Edge settings, in this case, there will be a banner "You're in Internet Explorer mode" like what you say. It's by design and we can' t remove it in this situation.
If you want the site to run in IE mode and don't want to show the banner, I recommend you can configure IE mode policies to load sites in IE mode. If you set the policies according to the doc, sites in Enterprise Mode IE website list will load in IE mode automatically without the banner.
Regards,
