I don't believe you can. The underlying proj libraries (as used by QGIS) no longer support longitudes > 180 by default, so any re-projection from EPSG:4326 will only work with +-180 longitudes.
There isa command line parameter (+over) which can be used with proj on the command line but I don't think this is supported by QGIS. If you use Postgis (or Spatialite), there is an ST_ShiftLongitude() function that will switch +-180 to 0-360 or the reverse which makes the operation pretty trivial for any sort of geometry. I have created a custom QGIS/Postgis projection (many years ago) which I assigned a code of 4327, this was essentially 4326 in a 0-360 degree space, so I could reproject between them, I'm not sure if this is still possible with the latest versions of proj with wkt definitions.

However, since the EPSG 3995 has limits of -180/+180 for longitude, as expected it gives half the plot. For some reason I cannot create a custom projection with an extent such as: xmin=0, xmax=360, ymin=60, ymax=90 based on 3995 even removing reference to this ID. Any ideas how to proceed without having to shift it all to +/- 180 Tested in 3.20 and 3.24 Thanks Lester [https://www.niwa.co.nz/static/niwa-2018-horizontal-180.png] <https://www.niwa.co.nz> Brent Wood Principal Technician - GIS and Spatial Data Management Programme Leader - Environmental Information Delivery +64-4-386-0529 National Institute of Water & Atmospheric Research Ltd (NIWA) 301 Evans Bay Parade Hataitai Wellington New Zealand Connect with NIWA: niwa.co.nz<https://www.niwa.co.nz> Facebook<https://www.facebook.com/nzniwa> LinkedIn<https://www.linkedin.com/company/niwa> Twitter<https://twitter.com/niwa_nz> Instagram<https://www.instagram.com/niwa_science> To ensure compliance with legal requirements and to maintain cyber security standards, NIWA's IT systems are subject to ongoing monitoring, activity logging and auditing.
