What exact BIOS version are you using?Because I try to install 10.15.4 to a beta SSD that I have, I couldn't proceed the installation. Stuck apple logo.
The method for me is to download 10.15.4 to application folder. After that open terminal and give
sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled
Where Untitled put the name of your USB.
It will take about 15 to 20 minutes to complete it.
Then we have to install clover bootloader 5107 to the USB, we can found it here https://github.com/CloverHackyColor/CloverBootloader/releases/tag/5107
We have to change the install location to our USB and same settings as shown above.

When the installation completes you should have an EFI partition mounted.
Download the following EFI folder and replace it.
After this you will be able to install Catalina 10.15.4. All USB ports on the back is enabled with custom SSDT.
When the installation of Catalina complete you have to install clover 5107 to the main SSD and again replace the EFI folder with the one attached.
What are your BIOS settings?
