Define S3 vsicurl for raster proxies

Is there a way to manually define the s3 vsicurl?

Currently my raster proxies are created with the following vsicurl:

> http://bucket-name.s3.ap-southeast-2.amazonaws.com/...

However these will not view in ArcPro, unless I manually change the vsicurl to the following, then they display perfectly fine:

> http://s3.ap-southeast-2.amazonaws.com/bucket-name/...

My OR command is as follows:

`python.exe C:\Image_Mgmt_Workflows\OptimizeRasters\OptimizeRasters.py -config=C:\Image_Mgmt_Workflows\OptimizeRasters\Templates\Overviews_to_MRF_LERC_pr.xml -input="C:\..." -clouddownload=false -tempinput=C:\... -tempoutput=C:\... -cloudupload=true -clouduploadtype=amazon -outputprofile=profile_name -outputbucket=bucket_name -output=path -cache=C:\i... -rasterproxypath=C:\...
