The issue is fixed in 2021.04 (experimental) which has the same default environment as 2021.01.
The upstream commit that fixed this is https://github.com/u-boot/u-boot/commit/82d01f04facef1276cede067efd02d2a731ffe83It applies cleanly on 2021.01+dfsg-4. Please include it or change the config for the affected boards not to try EFI bootmanager.
