Custom List Form creation using Powershell - SharePoint 2013

Question

Hi,
I have a custom List called 'IssuesList' with 4 fields - "IssueTitle","IssueID","IssueDesc","Status"
While displaying display form I should show 3 fields expect Issue ID i.e. IssueID should be hidden.
and on edit form only Status field should be editable. So using SharePoint designer I created respective Edit form and display forms and changed XSLT to control the display mode on the fields.
I have everything scripted in powershell till now - creation of custom list, publishing pages, webparts etc. however I am looking for how to provision or associate these 2 list forms with IssuesList after I create the list in new site.
I have restrictions on using wsp and site/list template due to business needs. So I need to know if there is any way I can upload these 2 files after I create custom list in powershell and associate them as defaultdisplay and defauteditforms?
Please advise.

Hi,
Per my understanding, you might need to apply these custom forms to a list after list creation using PowerShell.
With PowerShell with SharePoint Object Model, we can hide fields on list forms.
The similar thread below with code snippet will provide more information about this:

If there may be other requirements except for hiding fields, as you have limitation on using custom solution package(which should be preferable in such scenario),
a workaround I can provide is that, after list creation, you can add Content Editor Web Part contains the CSS style or JavaScript to the form pages of a specific list, it will help you hide/disable the specific elements, this can be achieved programmatically.
The code below can add a Content Editor Web Part to the DisplayForm of a list(though in C#):
public static void AddCEWP()
SPLimitedWebPartManager manager = null;
SPFile file = null;
using (SPSite site = new SPSite("http://sp"))
using (SPWeb web = site.RootWeb)
try
web.AllowUnsafeUpdates = true;
file = web.GetFile(web.Url + "/Lists/List018/DispForm.aspx");
manager = file.GetLimitedWebPartManager(PersonalizationScope.Shared);
ContentEditorWebPart webPart = new ContentEditorWebPart();
XmlDocument xmlDoc = new XmlDocument();
XmlElement xmlElement = xmlDoc.CreateElement("HtmlContent");
//xmlElement.InnerText = "<strong>Hello World!</strong>";
//write the custom CSS style or JavaScript here
string content = "<style>your custom style here...</style>";
xmlElement.InnerText = content;
webPart.Content = xmlElement;
manager.AddWebPart(webPart, "Top", 0);
manager.SaveChanges(webPart);
web.Update();
catch (Exception ex)
//Utility.SPTraceLogError(ex);
finally
if (manager != null)
manager.Dispose();
web.AllowUnsafeUpdates = false;
