Is there any way to install delphi 10.4 package into Delphi 10.3?

I am very new in Delphi vcl development. My question might be very armature type but I need your help. Is there any way to install Delphi 10.4 package into Delphi 10.3?

You have to recompile the 10.4 package source code with 10.3 hoping that the code doesn't use any new feature.

Package binaries are specific to each compiler version.  10.3 can only use packages that have been compiled for 10.3, etc.  If you have the source code for the 10.4 package, you will have to compile it using 10.3's compiler.
