I want to annotate my vcf file using Annovar and GRCh38 as reference. Does annovar supports GRCh38? How can I use GRCh38 for annotating my vcf file?

Yes, ANNOVAR supports hg38/GRCh38. You just have to install the databases by downloading them. Take a look here: http://annovar.openbioinformatics.org/en/latest/user-guide/startup/
For example:
annotate_variation.pl -buildver hg38 -downdb -webfrom annovar avsnp147 /Programs/ANNOVAR/database/humandb/
This will download dbSNP version 147 with hg38 co-ordinates to a directory called /Programs/ANNOVAR/database/humandb/. You can have multiple databases on your computer for each of hg18, hg19, and hg38.
When you then execute a further command to actually annotate variants make sure that you always use -buildver hg38 in the command, but you can flexibly use -buildver hg18 and -buildver hg19 if you have those installed too and also depending on the genome build of your data.
I couldnot able to download these two datasets in ANNOVAR
perl annotate_variation.pl -buildver hg38 -downdb genomicSuperDups humandb/
perl annotate_variation.pl -buildver hg38 -downdb -webfrom annovar snp138 humandb/
Is this is appropriate datasets for hg38? I'm newly using this ANNOVAR tool. PLEASE HELP!!
